"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!"

Basement Waterproofing FAQs, answered by experts

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.
