Basement Waterproofing, Crawl Space & Foundation Repair experts since 1991. Free estimates & inspections.

"I had a basement waterproofing project done by TC Hafford in March costing over 19K. It is now July and my basement is full of water, once again,on this rainy day. I have been back and forth with this company for months, and after sending someone in who finally admitted to faulty installation, I am still waiting for them to fix their mistakes. I absolutely would never recommend this company to anyone."

Concrete is everywhere- it is the material of choice in heavy construction and foundations. It's sheer mass and compressive strength make it one of the most substantial materials ever. But, concrete is prone to cracking from shrinkage and settling. Freeze/thaw cycles, heavy equipment, and blasting can also cause damage. Concrete Prescriptions has the unique ability to repair any resulting defect efficiently and effectively.

For more than 30 years, we have provided long-lasting and cost-effective foundation repair, wet basement repair, foundation concrete crack repair and basement waterproofing services in New Hampshire, Maine, and Massachusetts. If you are a homeowner, property manager, structural engineer, home inspector, or builder, you have probably experienced the problems caused by leaky basement and foundation walls. Leaking walls in your home or business, if left untreated, can lead to more serious and costly damage down the road. Water in the home can lead to mold, mildew, poor air quality, and further health issues. Structural damage may occur.And,even if water is not an issue, cracks can invite insects in to a home.

"Went well up front. Careful of there ten year guarantee. Had them come so we could finish our bathroom in our basement. We Finished our basement after they finished their work. Five years later the leak reappeared in the exact spot it was when we first contacted them. When we called to tell them about the leak, they told us we have to rip apart our 8K bathroom to prove them it was their work. The leak was in the same spot when they originally came out. Because of this I would not recommend them. The rip out and the replacement is on our dime. I think the guarantee is very Limited."

Black Bear Landscaping performs a wide range of projects. Included are outdoor hardscapes to total project designs that encompass patio, irrigation, lawn installation, flower bed designs, driveway and fencing. Black Bear Landscaping offers all landscaping services at competitive rates. Employees range from 3 to 10 and we occasionally use subcontractors when necessary. Larger contracts pricing allows for 1/3rd down, 1/3rd mid project and the final 1/3 at project completion.

"It went terribly. The owner promised his company was better than the others in the area because he uses 4-5 inches of topsoil, where his competitors use 2 inches. He talked up the seed that he uses, and that after installation in June of 2020, he would be back in the fall to weed and feed (which they did), and after all the trouble we had, said he would return in the spring of 2021 to fix it. That did not happen. What we got was 2 inches of topsoil,barely enough to cover some stumps we had ground, weeds, lots of weeds, more weeds than grass, then came the crabgrass which choked out any seed he put down. He did not come back this spring, so now our front yard is weeds, clover, some grass, crabgrass, and no grass growing where the three stumps were. And he tried to charge us for extra topsoil! I would never recommend Black Bear Landscaping."

Basement Waterproofing questions, answered by experts

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.
