"Western Construction did a great job of inspecting our property, explaining how they would do the job and found things we were not aware of. Although they were not hired do the job for me, I would have hired them; they submitted a decent bid and were customer friendly."

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Basement Waterproofing questions, answered by experts

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
