"He did a great job of replacing my front porch steps. He replaced with Trex decking. My steps were a little out of position and now they are straight and look wonderful. There was a nest of wasps under my porch. He fogged under the porch because they were too far back. When I need something else done I will definitely use him again. He was prompt and kept me informed. "

"I do not recommend this company due to poor quality of product. - Jan 2023 bought 2 patio doors, 3 slider windows. Product that was installed in May included 2 cracked slider windows and all products had wrong color on interior. All needed to be replaced. - May 2023 bought additional 19 windows. After install in Oct 2023, 13 of the 19 had noted manufacturing defects requiring replacement in January 2024. After install of these replacements in January 2024, additional 7 had noted manufacturing defects requiring replacement in April 2024. At install of these latest replacements, 5 more had noted manufacturing defects requirement replacement (which has not yet happened) - June 2024 during rainstorm noted two of the window sets had significant water leaks. Company was advised with documentation on 6.4.2024; as of today 6.8.2024 company has yet to acknowledge my request for refund so I can re-replace the windows with a different company. Additionally several of the caulk lines were obviously done by a new employee, as I had to have the contractor installing new siding re-do those lines."

We have been avid RV'rs for nearly 30 years and have owned several different types of RV's. Everything from a pickup with a topper and air mattress to a pop-up pickup camper, hard side pickup camper, travel trailer, 5th wheel and destination (park model) trailer. Discounts available for active or retired military, law enforcement, EMS and Fire Service personnel. It's our Everyday Heros Reward. We are committed to providing our customers with the best RV tank cleaning and system services possible. We take pride in our work and strive for excellence in everything we do. We are a family owned and operated business. Our main service involves using our specialized hydro jetting machine to clean the gray and black holding tanks in your RV. We essentially scrub the interior of your RV's holding tanks clean, getting them as clean as they were when the RV left the manufacturer, using 1500 PSI water (which does not damage your RV's tanks or plumbing system). Approximately two hours are needed for this operation, depending on the quantity of tanks and the seriousness of any issues discovered. The best thing about Minnesota RV Tank Cleaning is that in addition to cleaning and servicing your holding tanks, water heater tank, freshwater tank, waste system, and plumbing system, we also provide you with the knowledge and skills you need to maintain their condition.

Ive worked for a property management company for three years and have learned how to do just about repair in a home. My strong points are in flooring and plumbing. I will never leave a home owner unsatisfied with the work I do and never cut corners on jobs I have in front of me.

Boiler Repair questions, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Generally speaking, yes, turning one radiator off does save some money, especially if the system is a little older—so long as you’re not cranking up the dial on the ones you leave on. But some HVAC specialists argue that keeping your entire system on ensures that your boiler stays efficient. After all, it’s rated to fit your home and heats the amount of water your heating system needs. This could be the case if you have a new system. However, turning radiators off in unused rooms lowers the amount of hot water you need.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.
