"We couldn't be happier with Dave's overhaul of our fireplace. His attention to detail, and commitment to excellence. We feel so lucky to have found him after another contractor flaked out on us. He came to the rescue & did whatever it took to get the job done on time and on budget. He is highly skilled and capable. Several times during the job he suggested things that would enhance the finished product. In doing so he created more work for himself. These upgrades probably added a full day of additional work. He didn't change the cost for the job, he just wants his customers to be happy. His attention to detail and cleanliness blew our minds. He spent a full day getting the room taped off to prevent dust from spreading throughout the house. A full day!?!? And it paid off when the work was done...we're not even hiring a cleaner. More than anything Dave's got a good heart, my wife and I genuinely enjoyed meeting and working with him. (Note: no AI was used in writing this review!)"

We bring something completely different to basement waterproofing and waterproofing in general. We are not the company to call if you have large amounts of water entering your foundation or basement. However, if your foundation is in somewhat decent shape and un-painted. We can stop the moisture from seeping through your walls and floor that cause stored items from being covered in mold and mildew and make your basement far healthier and a truly usable and dry space permanently. With a one-time application using 100% green products that do not change the surface of your concrete surfaces. You can safely store items or furnish your basement and even install hardwood flooring with confidence. Our waterproofing works by using crystalline technology that enters your concrete going where the moisture goes deep into your concrete walls and floors. When moisture is present these crystals expand up to 16 times their size sealing the moisture out of your basement including cracks and joints.

"He has done a ton for stone walls for me over the years. He has always done an excellent job for me over the years. He is one of those rare people who does everything to the best of abilities."

Groundworks provides dependable foundation repair, basement waterproofing, concrete lifting, and crawl space solutions for Massachusetts homes. Our commitment enhances the value and safety of homes within our community.

"My professional came in to do a maintenance check up on my sub pump. To begin with they showed up on time explained what they were going to do and followed up with me after the task was completed during this time. My house was left on damage and you would not even know that they were here. I would recommend this company just based on my own personal experience with them. Not only would I recommend the company, but I would also recommend Alvin Miller, who is very professional in the way he came in, did the job and left without wasting any of his time or mine. Look forward to seeing him again next year."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Chelmsford, MA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
