Crawl spaces are often overlooked, but they play a major role in the health and stability of your home. In many homes throughout Weymouth, MA, crawl spaces are highly vulnerable to moisture buildup. When moisture collects under your home, it can create a wide range of problems that affect both the crawl space and the living areas above it.
Excess moisture in a crawl space can lead to buckled hardwood floors, condensation on surfaces, wood rot, and damaged insulation. In severe cases, insulation can become soggy and begin to hang or fall from the floor joists. Moist environments also attract pests and insects that thrive in dark, damp conditions. Over time, these issues can weaken structural components and reduce the comfort of your home.
With more than 20 years of experience in the construction industry, Don and his team understand how damaging uncontrolled moisture can be. As experienced waterproofers serving Weymouth, MA and surrounding communities, they have seen firsthand how moisture, groundwater, and trapped gases can affect a home’s structure and indoor air quality.
Unlike many waterproofing contractor companies that focus only on surface fixes, our team takes a complete approach to crawl space protection. We focus on controlling the climate inside the crawl space so moisture cannot build up in the first place. Proper moisture control helps preserve the materials under your home and improves the overall health of the indoor environment.
Our team carefully evaluates the condition of your crawl space before recommending the right solution. Factors such as groundwater pressure, ventilation, insulation condition, and drainage around your foundation all play a role. By understanding these elements, we can design a waterproofing plan that protects your home for the long term.
A Waterproofing Company Dedicated To Protecting Your Home
At Isabel Construction, we believe that effective crawl space waterproofing starts with addressing existing moisture problems and preventing new ones from developing. Our team can repair damage caused by long-term moisture exposure and then seal the space properly to stop additional water intrusion.
One of the most important parts of crawl space protection is installing high-quality vapor barriers. Vapor barriers create a strong protective layer that prevents moisture from rising through the ground and entering the crawl space air. When installed correctly, they significantly reduce humidity levels and protect wooden structural components from rot.
We also install professional dehumidification systems designed specifically for crawl spaces. These systems help regulate humidity levels year-round, even during the humid summer months common in Massachusetts. By maintaining a controlled environment beneath your home, we can prevent condensation, mold growth, and unpleasant odors from spreading into the upper floors.
Our team uses only high-quality materials and reliable installation techniques. The goal is to create a sealed, controlled crawl space that protects your home from both moisture and harmful gases. Proper sealing can also help improve indoor air quality, since air from the crawl space often circulates into the living areas above.

What Clients Say
Your opinions matter!
- We needed structural repair work to a beam and support columns in our basement. Isabel construction did an incredibly thorough and high quality repair. They paid attention to the little details, for example--to get to the beam some paneling needed to be removed. They could have cut through it badly and instead they cut it in a very neat and clean line so it looks as if it was always installed to terminate where the beam starts. They worked well with the structural engineer, kept the work site clean, left the basement with zero mess, and also were very easy to communicate with and were very responsive. I would 100% recommend them and would use them again for any other construction work my house needed.read moreread lessDeon W.5/19/2025
- Don Isable is truly a structural repair expert, and I feel incredibly fortunate to have chosen him as the contractor for our foundation project. As the project progressed, we encountered some unexpected challenges, but Don managed to bring in plumbers and electricians promptly to keep everything running smoothly. He handled all the structural inspections professionally and passed them with ease.
Given the significant sinking of our building's foundation, Don had to construct steps within the basement. He carefully balanced both safety and aesthetics, providing the best possible solution for our basement. His work is of outstanding quality, and his professionalism is unmatched. I wholeheartedly recommend him – absolutely deserving of 5 stars!read moreread lessFlora5/19/2025 - I highly recommend Isabel construction. When we moved into our new home we were told they had never taken water and the dehumidifier was new. Well, they lied. Don and his crew installed a French drain and sum pump, which has been a life saver. Last year our dehumidifier crapped the bed, so we called Don back and he came back that week with a new one for us. They were super professional and the office manager gets back to you right away. 10/10 recommend! ⭐️⭐️⭐️⭐️⭐️read moreread lessDonnamarie V.7/22/2024
- Don and his team made structural repairs and replaced the mortar of the field stone foundation to my 90 year old house. Don was a pleasure to work with - he was very respectful and courteous, and the quality of the work and cleanup were excellent. I can't recommend him highly enough.read moreread lessW. J.6/18/2024
- Clean, professional, and fair. Did a great job filling a basement foundation crack that was letting water in. Could not be happier with the results of Don and his teams hard work.read moreread lessAmanda C.5/15/2024
- We hired Don & his team in April to waterproof our basement walls because they were literally deteriorating and leaking water into our basement due to the age of our house. They did an amazing job, and we are very pleased with their work. Highly recommend these guys!read moreread lessHeather T.9/15/2022
- Isabel Construction impressed on all fronts throughout a nearly 8 month bid and construction schedule. All work was completed with diligence and professionalism, most notably in dealing with added scope as the work unfolded. Excellent communication, top quality workmanship, and fair pricing have ensured that we will be reaching out to this contractor again for any future work within his field.read moreread lessJeff N.7/02/2022
- Don was great to work with. I struggled to find someone that would even come down and look at the original job. Many had said they would come and just never showed up. Don said he would come a few days after I talked to him and showed up. He installed a sill under our front door (original job), put in a new sump pump and a new steel beam to secure our sagging main beam in our basement. I asked about his thoughts while I had him here on the other things. He explained the process while doing each job. The time of the year (Thanksgiving and Christmas) he was working here made some issues with doing the job when originally discussed but it got done and we were happy. He communicated each time there would be a delay so I felt like he wasn’t just ignoring our job. I would call them again if I needed. Very professional and nice.read moreread lessTracy k.7/23/2021
- Isabel Construction is the type of contractor you hope to find but never do, and me being a licensed architect I've worked with many contractors. Isabel repaired my foundation ( a major bit of work )they also are doing headers, new flooring, porch repairs, and some other odds and ends and every step has been great. They tell you a price and stick with it. They do work, but ask questions as needed along the way so the outcome is as desired. They also ask questions that arise during the work so everyone's on the same page, especially if when these questions affect future work where other contractors would just complete the job and kick the can of problems down the road. I Highly recommend using Isabel Construction and at minimum, for your own benefit, you should interview Isabel for your proposed work , compare them to others, and see if Isabel is a good fit for you. I have always been a good judge of character, something i find very important, and from the moment I met with and started talking with Don, I had the feeling that this was an honest, hard working individual, and through his work he proved me right. Great Work done at a fair price..done on time...construction debris cleaned up daily...and a great finished product. thank you Isabel constructionread moreread lessjon s.7/23/2021
