"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"When we moved into our new home, the one area that needed improvement was the tub and shower. Both were original fiberglass that had seen better days, and both had old glass doors that were deteriorating around the edges. Steve came out and gave us an estimate, explaining exactly what he would do. He also gave us local contacts to buy the tile, and fixtures. Workers showed up on time, laid out dropcloths on the floor and cleaned up after themselves everyday. Work went right on schedule with the timeframe Steve said. Finished product went beyond are expectations."

"I think that Tom and his workers did an excellent job on our installation. They knew exactly what our particular problems were, and installed a superb system for us. I couldn't be happier and would recommend Tom's Environmental Care as a first choice for anyone needing sprinkler systems."

"Worked with Jake primarily as he did the plumbing portion, and another gentleman did the drywall. Good communication, prompt, very professional and overall pleasant to work with. Price is on the mid-higher end, but I felt very confident in the reliability of the finished job, plus they got the work done quickly. If I had to cite one small cosmetic negative it would be that the top edge of the box is a tiny bit less than level, though the walls in that laundry closet were never quite straight to begin with. Would go through them again and consider for other home projects in the future."

Basement Waterproofing questions, answered by experts

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

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.
