Got Questions? We’ve Got Honest Answers.
Someone told us that they would do exterior waterproofing to prevent the water from reaching the basement. Is this a good idea?
Exterior waterproofing is often unnecessary and more costly. Pipes placed in the ground around the home become clogged and cracked because they are still exposed to the original conditions that caused the water to enter your basement. Soil settling is inevitable, and any pipes or tile installed in this environment will clog and break. Most projects take 1-3 days depending on the size and complexity of the work required.
What type of warranty do you have?
Waterproofing is warranted for the home’s life and is a transferable warranty. Foundation work depends on the type of work we do. We assure you we have the best warranties in the industry, at absolutely no charge to you. We feel that the peace of mind you gain from our work should be free.
Will this type of work increase the value of my home?
Definitely! This will not only enhance the value of the house, but the home value will also increase by more than the cost to fix it
