"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 questions, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.
