"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!!"

"This is the 5th or 6th time Western Rooter and Plumbing does a plumbing job in my house over past 10 years. They installed softwater tank, replaced waterheater, fixed plumbing, and more. Always excellent"

Backing up? Got roots? Blast those roots out with a Hydro Jetter! We use a wart hog nozzle that combines controlled rotation with a unique 8 jet cutting configuration optimized for removing roots. It’s better with a jetter! Call us! We got this! ??

"Samuel is great - he’s done work at our condo a few times and I will absolutely hire him again and recommend him to others. He’s always respectful of our home, always helps me understand all of the options to solve the problem, and never tries to take advantage of the fact I know absolutely nothing about plumbing. For ex: He came to our house last week and charged me less than he had quoted me because the work was easier than expected."

"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!"

"Tony and his crew arrived on schedule, worked hard and did a great job on a complicated roof. The workers were pleasant as well as skilled. Very satisfied with both price and result. Would use again for other construction services they provide. Roof will outlast me."

"I would definitely recommend Thomas Parks.  He and his team arrived on time, and completed the job of cleaning my gutters in a most professional and respectful manner.  Mr. Parks explained to me in detail all of what he would be doing and why.  He even went above and beyond.  (Note: It was Mr. Parks who originally installed some of my ground gutters more than a decade ago.)
After doing business with Mr. Parks that day, I hired him to do my Roof Waterproofing with Kool-Seal Coating.  Again, I was very pleased with Mr. Parks' work.  I would enthusiastically hire him again for future work on my house.  In fact, he and I have talked about putting a new roof on my shed out back.  Thank you, Thomas Parks.  I look forward to working with you again soon.

Basement Waterproofing questions, answered by experts

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

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.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.
