"Century Masonry sent personnel to remove existing sheetrock and insulations on the first day, and then on the second day, installed the needed reinforcing strips and finish their portion of the restoration. They worked quickly and professionally to correct the problem and allow my family to have peace of mind."

"Jeff, Rob and his crew were exceptional They answered all of my questions even took the time to show me how things worked. They installed a water catch basin and sump pump to replace our smaller 25 year old equipment. Jeff suggested a better pump They were meticulous in their work and cleanup except for the new pump you would not even know they're there. I would recommend ONCE&DONE for any of your waterproofing needs Thank you ONCE&DONE"

"They explained their system and the installation process in detail. They were very flexible and worked with our schedule to finish installation of French drain system before sale of house. Extra foundation work was needed, and they did that as fast as possible"

"We interviewed several waterproofing companies for installing a French Drain. We are in NE Philly where the water table is so bad. We get water in our basement with nearly every major rainstorm. After 2 storms dumped 7" in 3 hours and another that dumped 4" 2 days later, we'd had enough after 13 years. Ryan came out and did an inspection and showed us what our basement needed and what Dry Tech's installation would do. He answered a lot of questions and did great follow up with us, without being pushy on hiring his company. After meeting with other contractors, we gave them the job. The workers were thorough, courteous and professional. They took all the steps needed to cover and protect our things that were in the basement and cleaned up everything afterwards. The job took 2 days. While I can't YET state how great the drain works, I'm actually looking forward to the next big rainstorm"

"Water damage from behind patio flashing caused a full replacement of 20 fr of sill plate, sheathing and concrete replacement with correct slope to ensure water drains away from home. Sam and his crew did an excellent job - arrived on time and finished with quality product. House needed to lifted to remove sill plates and it was done professionally. Concrete placement was done with high strength concrete and rubberized flashing used on all pressure treated wood that was replaced. Galvanized nails and screws were used with pressure treated wood. And all cement shingles were replaced and sealed. Long days and quality work at a fair price. Home is now secure from water damage for the future."

Drain Pipe Installation FAQs, answered by experts

Coke and other sodas do clean a clogged drain, so this is one of those urban myths that has some truth behind it. Coke and similar sodas are caustic and will provide some cleaning power to your drains. However, the power of soda pales in comparison to dedicated cleaners or even baking soda.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
