We specialize in all phases of remodeling for your home, business, bathrooms, kitchens, finishing basements, and more! We guarantee your satisfaction, and we won’t leave until the job is done right. We pride ourselves on the quality work we provide, while delivering great customer service! Check out all the services we offer below and call -or- click to schedule a free estimate today!

"In hindsight, I believe we were charged anywhere from five to $8000 more than what we should’ve paid. We had a walk-in bathtub installed and while I like the bathtub, the overall cost was excessive. We prepped the bathroom and removed the old bathtub so they did not have to contend with any remodeling or removal of old construction. The plumbing itself did not have to be moved so the only thing they had to do was deliver and install the tub. I would recommend for anybody using this company to not succumb like I did to the pressure buy. If they’re going to install it, they should be able to give you a quote that they standby as you compare prices with other installation companies. After the installation was completed, we did all the backsplash tiling ourselves as well as decorative tiling around the base of the tub."

Boiler Repair questions, answered by experts

Regular inspections, filter replacements, and professional tune-ups keep the system running efficiently.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.  

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low.
