"I'd give so many more stars if I possibly could! We were so very pleased with the entire Rescon Basement Solutions experience. Bob came to our house and assessed our basement/bulkhead wall issues. We were involved in any decisions and were given a very honest, complete quote and a scheduled date for the work to be done. Unfortunately, before the scheduled date, we had a very heavy rain and water poured into our basement. Bob from Rescon gave us advice on how to handle that and Alexa was able to move the work date up to help us out of a big jam. Patrick, Jake and Tim arrived promptly to get the work started. They were very professional and explained absolutely everything they were going to be doing. They set up plastic tarps to keep the rest of our basement clean and did a fantastic job. When they completed the work, they went over all of the new equipment and explained everything to us. We were happy with every part of this project. Cannot recommend Rescon enough!!!!"

Common Causes of your Basement Problems in Londonderry

Foundation Cracks

Cracks in foundation walls or floors can let water seep into your basement, especially during heavy rain.

Poor Drainage Systems

Ineffective drainage, such as clogged gutters, downspouts, or poorly graded yards, directs water toward your foundation.

Hydrostatic Pressure

Water in the soil builds pressure against basement walls, filling the clay bowl, and forcing water through cracks and joints.

High Water Table

Rising groundwater during heavy rain or snowmelt can seep into your basement through cracks or porous concrete.

Faulty or Missing Sump Pump

Water from heavy rainfall or flooding can accumulate in your basement without a working sump pump.

Plumbing Leaks

Leaking pipes or fixtures near your foundation can saturate the soil, causing water to seep into your basement and cause moisture related problems.
