"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"All of the floor joists in my family room were rotted and/or collapsing due to prolonged water damage. Atlas staff, including the salesman Jim and engineer reviewed the situation and recommended a waterproof membrane and pitching the sidewalk on one side of the building away from the building. When water tested this only provided a partial fix of the problem. We eventually decided on drain tile and adding a concrete sidewall around the entire perimeter. This appears to have been the addition step needed. Only time will tell. There is a 10 warranty against water seepage. Robert and his team were great to work with. They were timely and responsive to my questions and concerns. The project took a little longer than expected due to having to add the drain tile and additional walk way."

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

Small jobs welcome

I’m Adam majority of my skills and talents are for outside your home. I have a career in underground construction where I replace, install, and fix pipes for water, sanitary, and drainage from 72” concrete pipe 1/2” sprinkler lines. If you are having issues with water drainage,septic or really anything underground I’m your guy. I specialize in in a wide range of landscaping such as mulch beds, garden boxes, trimming and removing bushes, and planting trees&bushes. Also I can trim or remove that old tree that has been an obstacle or eye sore for you. I grew up helping my dad and grandfather in their landscaping business. I started running a chainsaw when I was 9 yrs old. Patios, retaining walls, or flagstone for walkways or edging I can give them a fresh new look or I can install them from a blank canvas. Mother nature can be rough on any deck or fence over years and can become an eye sore or even dangerous I can give them new life for the summer. Hope to hear from you soon.

Basement Waterproofing questions, answered by experts

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

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.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

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.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option.
