"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

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.
