"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! ??

"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!"

"We have a 50 year old single family residence that was built in the 70s. The foundation needed repairs to restore it to its original strength, and retrofits to meet current earthquake regulations. I researched all the options to repair and retrofit the home. Sure Safe's was the best available. They installed 50+ brand new concrete footers and steel piers to secure the home. No other contractor offered a solution that was adequate structurally. Art was great to work with and answered ALL my questions. Elaine coordinated the entire process and the team of Sergio, Casey and Brock worked tirelessly to install everything in a single day. Wow! I'm very pleased with the work and the solution that SureSafe installed to keep our home safe and secure. Thanks!"

"Joseph is amazing. We have used him many times for years for multiple home projects including remodeling a bathroom, new siding on the house, new roofing, plumbing repairs (and emergencies). He has always responded quickly, his work has been excellent, the site is always left immaculate, his crew are always on time and very pleasant. Joseph's work is outstanding and we have never had any issues. He has helped us out fixing issues that predated him also promptly and done to only his high standards. We can not recommend him high enough and will use him for many years to come."

Basement Waterproofing questions, answered by experts

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.
