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.

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."

FAQs for basement waterproofing projects in South Portland, ME

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
