What to Update in a 20-Year-Old Home for now

If your home was built around 2005, it’s now approaching 20 years old. What to Update in a 20-Year-Old Home for now. That’s also the perfect time to evaluate systems, safety, and efficiency.
In addition Small upgrades today can prevent expensive repairs tomorrow — and boost your home’s long-term value.

Massachusetts homes face unique challenges from cold winters, humidity, and seasonal storms.
These conditions can shorten the life of roofs, HVAC units, and exterior finishes.
Regular updates keep your home comfortable, efficient, and safe year-round.

1. Roof and Exterior Update a 20-Year-Old Home

Most asphalt roofs last about 20 to 25 years.
Look for cracked, curled, or missing shingles.
Reseal flashing and replace worn gutters before leaks cause damage.
Check siding and trim for peeling paint or water intrusion.
Fogged windows or broken seals also reduce energy efficiency.

Closed on my house this month and only with the help, knowledge, skill, and easy-to-understand communication that Tom has.

I had not known how important it was until Tom that having someone who was actually in the business of construction is critical for a solid inspection.

I bought an old house, that's 2 units...twice the work and old houses well they have their own thing. So to compare I had one prior two unit house that was oh about 1.5 times bigger than what Tom had inspected...the previous 'inspector' took about 2 hours and left without even notifying me, made me feel like I was in the way if I dared ask a question while they tap tap tap on an iPad for my report. This previous inspector also gave a report (after inspecting another house that day?) to me that night...it was auto filled. Auto generated. Not detailed or customized to give me the in-depth I'd hope. "Could be this or could be that or could be the other thing or that other thing". Tom may give a report a bit later but it's because he actually puts his details to it. Not an auto-filled cookie-cutter report that isn't necessarily useful. And Tom spent a kindly 4 hours on my inspection! Phew! I was at least exhausted I can't imagine him.

Tom was there with me from outside, to the basements (which I know so well now thanks to him), to the kitchens, bathrooms, hallways, mudrooms, bedrooms, and attics. And all nooks in-between helping me really KNOW my house.

Most inspections nowadays are from hands who only type on an iPad and keyboard who took courses on 'home inspection', but I'd rather someone who's swung a hammer...and then some. He's an expert in construction, the ins and outs, inspection reports, in full detail with excellent photos, amazing communication, easy to work with...

Oh and I am a first-time homebuyer, he made me feel at ease! I wish I went with him on my first house inspection (that's another chapter in the past!)

He's going to be in your 'recommendation' book if you're lucky to find him and I can't imagine his level of availability in the peak season.
Thanks Tom!!

Great service/experience overall. Can really appreciate the straight forward honesty and full transparency during the home inspection. Tom definitely helped get a very detailed understanding of the home. Inspection report was very thorough as well. Would truly recommend Tom’s services for anyone that needs a home inspection!

Thomas was honest, thorough, and professional from start to finish. He didn’t just inspect the house — he educated me throughout the entire process. He called out what needed attention, gave context around the systems in place, and didn’t sugarcoat anything. That’s exactly what I needed to make a smart decision. If you want clarity, experience, and someone who genuinely gives a damn, Thomas is your guy. Highly recommend.

Thomas was great to work with. As a first-time homebuyer, he answered all my questions and went above and beyond to ensure I understood the condition of the house I was planning to purchase. After the on-site inspection, he even reviewed all the recordings to make sure nothing was missed. 10/10

Pleasure to work with. We had requested a home inspection as part of a inheritance so we were completely open to any and all recommendations.

Tom was extremely detail oriented, very in depth and very upfront with his inspection. Being a part of the building trade made it very easy to evaluate just how knowledgeable and in depth his inspection was.

If you are in the process of buying a home and want an honest, upfront and unbiased evaluation of the homes condition, I could not recommend anyone better than Tom.

As a bonus, Tom was able to recommend several programs to evaluate and provide tax benefits for the many programs available for tax rebates based on enhancing a homes energy conservation.

Cannot add too many superlatives. Tom was both upfront honest and supremely knowledgeable, something that was very refreshing in dealing with home inspectors from within the building industry.

Thanks

Tom did a great job, thoroughly going over the house and explaining to me, along the way, the issues he found along with many important points I needed to know once we bought the house. He gave me a good list of questions to ask the owners. I feel good that I know a lot more about the house and what to address now and in the future.

Tom is a very thorough inspector and he will list all the improvements and potential problems for the house. As a first time homebuyer it can be overwhelming to see the long list of issues, you might want to clarify with him what are the serious problems that needs to be addressed with the seller, and just keep that in mind.

I am completely satisfied with the roof inspection Thomas did for me. He was thorough and explained his findings clearly. Because I needed the inspection for insurance purposes my need was urgent and Thomas acted in a timely manner in both completing the inspection and producing a written report. The cost was reasonable. All in all a great value and I highly recommend him.

Thomas Herbst did a great job with our home inspection. Not only was he was extremely thorough, but when we weren’t able to go to the inspection he took the time to connect with us to review his findings. He was very personable and easy to work with. Highly recommend!

If your looking for a home inspection, this is the one. Had such a great experience doing a walk through with Tom. What a wealth of knowledge. Such a great personality as well. From the very first encounter with a firm handshake (finally a hand shake that felt like competition) it felt like I went to school with Tom. Great conversation made the hours go by fast. I highly recommend Clayton Home inspections Inc to anyone, whether it's your first home or third. Thank you Tom. It was an absolute pleasure to meet you and to have you share your expertise.

If you’re considering hiring an inspector in Middlesex County, do yourself a favor and hire Tom. Not only did he explain everything in detail, he has an in depth market specific knowledge that will make you feel more than comfortable in your decision. Great guy, great service, highly highly recommend him.

As a satisfied customer of Thomas, I highly recommend his home inspection services. Thomas came highly recommended by a friend who recently purchased a house, and I am so glad I took his advice. As a first-time homebuyer from China, I was unfamiliar with the nuances of homes in the United States, but Thomas was incredibly patient and took the time to explain everything thoroughly until I understood.

Thomas is highly experienced, and it shows in the quality of his work. He was punctual and conducted a thorough inspection of my new home. His attention to detail and expertise in the industry was evident in the detailed report he provided, which was instrumental in negotiating with the seller.

What impressed me the most about Thomas was his willingness to go above and beyond to ensure my peace of mind. He didn't hesitate to spend extra time on my case, which is a testament to his dedication and professionalism. It's no surprise that he has an excellent reputation in the industry, and many people recognize his work.

Overall, I would highly recommend Thomas for anyone in need of a home inspector. His professionalism, expertise, and patience made me feel at ease during this otherwise stressful process. Thank you, Thomas!

Tom did an excellent job inspecting a home we are purchasing in Middleborough, MA. This is the second time that we hired Thomas. He is an extremely well qualified home inspector with a lot of experience. He's seen everything in his career as a home inspector. He was extremely thorough, noting every detail, and prioritizing the items that required attention. No stone was left unturned. He fully explained everything in layman's terms. Tom produced the inspection report quickly, without introducing any delay in the purchase of our home.

I couldn't recommend Clayton Home Inspections any higher. We are first time home buyers, and had Tom inspect our house the day after we purchased it, one to learn if there were any immediate repair needs, and two to just learn how the house works. He was incredibly thorough and did an amazing job clearly explaining everything to us in an easily digestible manner. He also did a great job prioritizing near term items versus down the line items. He is an extremely nice person as well, and we thoroughly enjoyed our time with him. Tom came highly recommended to us, and I'm very glad he was the home inspector we chose.

We had Tom come out twice to look at a prospect home and our eventual home as well, both times Tom was on time and very very knowledgeable, not only providing us with information on the home but also offering several great recommendations to improve the home. He took many pictures and answered all of our beginner homeowner questions. Would definitely hire Tom again for a future home!

I called two other inspectors a week ago and still haven't heard back from either one. But I was able to get confirmation for a next day appointment on the same night.

Tom was ultra responsive and professional. When we arrived early the next day, he was energetic and enthusiastic to do the inspection. He stayed with us for three hours explaining the pitfalls and dangers of the home; everything from structural damage, insects, to water irrigation mediation and his visit to Rome. He made sure that I understood exactly what was meant every step of the way.

The inspection report was well detailed, and he even took time to give a personal summary over the phone. As nervous home buyers, my experience has never been better, thanks to Tom.

Thomas inspected the commercial building that I was purchasing in January. We closed on the sale in May and when I got into the building had several questions. I called Thomas and he took the time to answer all of my questions even after the inspection! He cares about his work and helping people understand what they are buying. Thank you Thomas!

I recently had a great experience working with Thomas from Clayton Home Inspection. He was thorough, responsive and competitively priced. He took the time to answer all of our questions. Even after the inspection was over, he still answered our phone calls and was happy to explain things. I have worked with inspectors in the past who were alarmists, but Thomas was able to communicate the issues on this property without making my girlfriend freak out. That was a huge plus. I highly recommend Clayton Home Inspection!

Thomas is the BEST! I have been using quite a few home inspection services in diferent states we lived. However, Thomas is the best of all!!! He is very detailed, professional, patient and responsible. He explained every problem for me in a very scientific way that I got a deeper understanding about my house maintainence in different situation.

Tom inspected the house we bought last year. He said to let him know if questions ever arise about the house. I reached out to him, and he opened his files and took the time to walk me through how to deal with a complicated issue. He is knowledgeable, asks great questions and gives good advice.

I highly recommend Clayton Home Inspection.

I am a scientist and my wife is an engineer. We relocated to Massachusetts for our work, and choose Clayton Home Inspection for our first house purchase in MA.

I had been disappointed by other home inspectors in the past, missing some pretty obvious issues, but the Clayton Home inspector carefully reviewed every accessible area methodically. The inspector discussed each finding in detail and put together an easy to understand report.

A good home inspection is very important for the older houses typical in MA. I would recommend anyone looking for a home in my area to go with Clayton Home Inspection.

Thomas was great! He set my mind at ease right away. In need of a last minute inspection for a refi. I scheduled my inspection within 3 days! He was prompt and very professional. He took his time and checked all areas in and around home relating to our issue. All of my questions and concerns were answered in a way I could understand. Very knowledgeable and patient. Gave us specific remedies to take care of our problem. Most Home inspection companies only perform full home inspections. Thomas did not hesitate to offer his services to inspect the area of our home that was required. He even responded back within hours with his official write up! I would not hesitate to call on Thomas in the future if needed and will highly recommend him to any friends or family in need of an inspection!

I got Tom's contact information from a friend of mine, who highly recommanded him. The experience of us through the whole inspection process gave the same impression. Tom is very knowledgeable and pays attention to very details, a bunch of things we never notice until he pointed out to us, he also shared a lot of information in regarding to the heating system and appliance usage, very helpful in the long run. I will highly recommand Tom too, five star profession

Tom was very punctual and kind. This was my first time home-purchasing inspection and he walked me through the details of how to maintain a home. Answered all my dumb questions in very kind manner.

Single family (attached) home inspection. Tom was on time, very easy to work with, and professional. He explained everything to make sure I understood the house.

Will use this service again! Money well spent. Tom was prompt (in fact, early), knowledgeable, and thorough. We were very close to buying an historical home, circa 1830's, that we knew needed major renovations, but Tom, gave us a view to what lay beneath the surface. His report was very detailed, and was provided quickly. We appreciated his experience and expertise in working with antique homes and are continuing our search. Special note: thanks, Tom for being so easy to work with especially during this covid-19 crisis.

Tom performed the inspection for the purchase of my condo back in October 2019. I have purchased 3 homes and Clayton Home Inspection is, by far, the best that I have dealt with. My closing was fast-tracked and I needed the inspection done quickly - Tom worked with me to find a convenient time (coming on a Saturday so that I didn't need to take time off from work, no less) and spent a significant amount of time and attention to detail during the actual inspection. The report he provided (very soon afterward) was complete and detailed. I would definitely use him again (although I hope I don't have to as I plan on this being my last and forever home).

This was my first experience with a home inspector and I am beyond impressed with the professionalism and care that I was met with. Tom was incredibly thorough and took great care to give details and insight into what he saw. He showed up early and I could not have asked for better service. If you are looking for a home inspector, look no further.

I was very lucky to hire Tom to inspect the house I was interested in. We had to get the house inspected very promptly and, fortunately, Tom had an opening for us within 48 hours, on a Saturday afternoon. We found Tom very knowledgeable (you can't beat 40 years of experience in this business!) He treated the house as if he was the buyer, so he made sure to address every potential issue. Tom also gave us great recommendations on how to make the house more energy efficient. He was very professional and pleasant to talk to. The inspection report arrived within 24 hours. Highly recommend!

Tom was extremely thorough, pointed out areas of concern to me directly (rather than me waiting for the report) and gave suggestions on how to economically remedy them. Seems he genuinely enjoys helping potential home buyers not waste money. Fantastic inspection. Highly recommended!

Tom conducted home inspection for me last week. He is the best Home Inspector I've ever met: extremely professional and easy to communicate to, highly knowledgeable and detail oriented. Tom provided us with a very thorough home inspection, gave many important advices. Friends and family recommended me to invite Tom for home inspection. Now I can confirm that it was a real pleasure to meet Tom. I recommend Clayton Home Inspection to anyone who is in need of a home inspection and home education. Tom, thank you so much for great job!
