"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!"

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote.  Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"When searching for a general contractor, I was looking for 4 core characteristics: expertise, reliability, trustworthiness, and fairness. Steve Pope of In-Line Construction embodies each of these, and as someone who is known for having exceptionally high standards, I could not be happier with our finished product. I was very thorough in gathering bids from several general contractors, and Steve immediately stood out as someone who is very knowledgeable in his craft, genuinely cares for his clients, and is committed to offering fair and competitive pricing. Throughout our project, his team would show up on time, work hard, and ensure that they cleaned up afterwards. Steve was always swift in his responses to my frequent communication, and stopped by at least every other day to ensure that all was going well. He even personally came to install our shower fixtures on July 4th so that we would have access 1 day sooner! Perhaps one of the things that makes him stand out most, is that unlike so many other contractors, he only charges you for the labor that he provides, and never up-charges for materials, but still gives you access to his discounts and retailer relationships. The quality of the work is outstanding, and for a very reasonable price. I highly recommend his services."

"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."

"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."

"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

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.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.
