"The crew were hard workers and got my basement waterproofed in only five days - I was pretty amazed at how fast they worked. Expert responds very quickly to all inquiries and it is very obvious that they care about the quality of their work and making sure their customers are satisified. It was costly, but it is fabulous to have a completely dry basement when it rains!"

"I just spent $220 with another company to fix the problems caused by one of BW Cookes plumbers. He has red hair. He installed a toilet and two faucets. On one faucet, he worked on it for four hours and two trips to the hardware store. I called them and told them he was incompetent and needed some help. They refused. All three fixtures quickly came loose and I just spent $220 with another firm to tighten his bolts for him. The next time a customer tells you that your plumber is in over his head, take them seriously and send someone to help him."

Insulation questions, answered by experts

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

The benefits of insulating your pipes include preventing freezing, sweating, and condensation. In addition, insulating your pipes can make your home more energy-efficient by keeping your pipes from losing or gaining heat. You’ll be able to turn the temperature of your water heater down by two to four degrees Fahrenheit. According to the U.S. Department of Energy, this can reduce energy costs by 3% to 4% per year.

Air duct insulation lasts between 10 to 15 years. How long air duct insulation lasts will depend on the material it's made of and ongoing maintenance.

To extend the life span of duct insulation, consider inspecting it periodically for signs of deterioration, water damage, or general wear and tear. Even if the insulation is in good shape, some homeowners might consider replacing it with newer, more energy-efficient insulation.

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.
