"Five Star Bath Solutions of Fort Collins just finished our hall bathroom remodel and I'm still a little shocked at how different it looks. Their crew was friendly and efficient ? he replaced a pedestal sink with a two-drawer vanity that finally gave us storage, swapped the dated brass fixtures for matte black, and retiled the floor with a classic black-and-white hex pattern. The whole job came in at the quoted price and was done in two days. We're off Timberline Rd and I've recommended them to everyone on our street."

"I used this company to fix a leaky pipe in my basement and he did such a good job that I also had him service my boiler. I usually do my own repairs at my house but I did not want to risk having a water line break and flood my basement. Will definitely use again."

Percolation Tests questions, answered by experts

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

DIY kits are available, but professional testing ensures accurate results and compliance with regulations.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.
