"To summarize quickly, I cannot speak highly enough of Diggs Building Technologies. I am absolutely blown away by what they accomplished and would hire them again without hesitation. Worth every penny. For the past 5 years, I have been restoring/rennovating a 1890 Balloon Frame Colonial in Tillson, NY. While the original house foundation was extremely well built and well-mainted, I canâ t say that much about the 2 story enclosed porch put on in the 1920â sâ ¦ The foundation was crumbling; the first floor walls were bowing out and the floor had settled 3+ inches. To further complicate the matter, all the mechnicals of the house (water, sewage, and gas) ran through that back porch foundation making the project extremely complex in scope. Despite these massive issues on the first floor, the 2nd floor of the porch was in great shape and it was important for us to find a builder who could rebuild the entire bottom half of the structure while also preserving the top. This was no small feat. Much to my surprise, Tim and his crew (alongside their engineer) were able to do just that. With precision, they navigated the mechanicals, removed the old foundation and floor and then went on to replace both of those elements. While doing this, the room above stayed untouched. Not one crack on the walls, not one bow in the floor, and shockingly - all 4 of the original casement windows still opened and close. Overall, they did an excellent job and I would hire them without hesitation again. If you are dealing with any foundation issues, I encourage you to hire Tim, Jake, and Jesse. They are the only team I would trust doing this type of work."

"Sometimes you just get lucky. We got super lucky when we hired D. Rohde to fix our A/C. Our technician Mike A. showed up with a helper/trainee, explained the estimate fees and then went to work. In less than 10 minutes he was able to identify the defective part, return to the truck for a new replacement part, and then install the new item. In under 30 minutes our main central A/C was back up and running. The second (upstairs) central air unit took another 10 minutes to diagnose and then about 40 minutes of grueling work in a super-hot attic to drain out the overflow tray, cut, blow-out the drain line, and repair the drain. Once drained, the unit is again working perfectly. It is great when a technician shows up and really is an expert. Mike A. is such an expert and also extremely friendly. Brandon, the assistant/trainee was also great and someday will make a great technician using all the knowledge learned from Mike's expert tutelage. I will recommend these guys to everyone I meet."

"Anthony arrived at the promised time. He worked to clear a basement drain clogged with hardened grease, and had to use two different sized electric augers to gain access to the problem from two directions. He thoroughly explained prospective costs in clearing this clogged cellar drain before he started work in October 2015. The man knows how to use his equipment well, yet he worked for two hours before completing the job. His fee was reasonable. But in June 2016 the same job was less complicated than before, required less time and was done during the normal business day (about noon), and not after 5 pm as during the first call, yet the charges were noticeably higher. It is better to get an estimate before you agree to any project."

Foundation Drain Installation FAQs, answered by experts

Costs depend on pump type, labor, and site-specific requirements like excavation or drainage lines.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

There are a few possible sump pump drainage locations, including a neighborhood storm drain, into a creek or pond, or underground. Don’t let your sump pump water go into your sewer or septic system. Ideally, your drainage spot should be on a downhill slope that’s at least 10 to 20 feet away from your home’s foundation. Before choosing a location, check your local codes and regulations.
