"Great company to work with, very friendly knowledgeable people and customer satisfaction is their goal. Matt and his crew did a superb job restoring our finished basement after it got flooded when our sump pump had failed during heavy rains. Dual pumps were installed, along with waterproof and mold proof walls and flooring and a Sedona dehumidifier air purification system."

"My rear facade wall was falling apart, there was apparent deterioration, cracks falling apart. I was recommended to High Tech by our community board. Scaffold was used for this project. They chipped out the 4-story facade and applied wire-mash. First coat of cement was for curing and the second coat was  the finishing coat. The finishing coat was very finely re-finished. The back-wall was waterproofed with thoro-coat.  My roof was leaking as well at multiple places, bubbles had been formed with water seeping in, leaving into my kitchen. The weather was very rainy and stormy at that time and thanks to High Tech they repaired my roof by placing a new layer roof on top of the existing roof and stopped the leak. High Tech remains as one of the top recommended company in our community board."

"J & J Plumbing installed a ductless AC/heater in our back room, and we couldn’t be happier. Even after an incredibly stressful morning (Josh’s truck was stolen from our driveway) he and his crew still completed the job! They were kind, knowledgeable, and professional. I would give them 10 stars if I could; they deserve it!"

Basement Waterproofing FAQs, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.
