Behold the Difference! Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".

"My water heater had gone out and called and called around trying to get quotes and big company’s were trying to schedule in person quotes which I know is a strong arm to get the work done then and there because they are already at your house ect. But with Behold I had a personal direct text from them asking about my situation and all I had to do was give some info send in pictures and voilà! They gave me their quote(2300$) which also beat all the company’s(3k$+) I had heard from! They had a tech out to me ASAP. It almost could’ve been same day but I was in no rush. Hunter came in and did it all him self of removal of old and installing new in just two hours! They are great to work worth and will definitely recommend and go to again."

KITCHENS ONLY. We are a full service kitchen remodeling company. (We do not do baths or other remodeling work by themselves, only with a kitchen.) I have a General Contractor partner who I have worked with since 2017 who does all the construction services while I do the design (in 2D and 3D) and provide the cabinets and countertops, which must sourced from us. Designs and Estimates are free of charge! As of 04/25 we have completed 125 kitchens together as well as a number of other interior remodeling work, like bathrooms, paint, drywall, flooring, etc. We have a great process down! We are also experts in structural work like removing bearing walls (and building beams) removing soffits or false ceilings, building new walls, pantries, etc. We do most of our work with our own crew, so we maintain our quality of work and control costs. We focus on the Denver metro area. Please call me today for your dream kitchen!

"From the moment we met Mike we knew we wanted to work with them. Mike was kind and knowledgeable! He and Ryan worked with us to make our kitchen dreams come true. They were patient with us while figuring out all the little details we wanted. The crew was timely and respectful of our home. I would absolutely work with them again and I recommend them to everyone I know needing remodels. 10/10 would hire again."

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."

Install Boiler questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.
