"Alford had waterproofed my basement 2 years ago & I've been very pleased with that project. This time, a mouse had gotten in thru an open garage door when weather started getting cold, and had found a hole in a cinder block wall and had babies! I had already trapped and killed 5 before calling Alford. The rep was very polite, professional, knowledgeable, etc. He quoted me a price which was very reasonable but I decided to wait & see...it's been 6 days since last one killed & I still have traps set throughout the house but if I have any further issues, I would not hesitate to call Alford!"

"Jodie Machen is an outstanding workman and job manager. Our home is a old steel-baron era mansion from 1929. It needed a new roof and significant association flashing work. Jodie Machen was the perfectionist I was looking for. Not only did he do an immensely careful job, but he was thorough in his communication with me throughout, calling to touch base not just on formal aspects of the job, but also on convenience questions. His personal presence on the job made sure that his standards translated to his work crew, and together they presented a polite and professional group who I felt very happy to have around my little kids. I would unhesitatingly recommend this company! As an aside, Jodie Machen also fixed a difficult plumbing problem for us, so I suppose he would be great for other similar work as well!"

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.
