We are a family owned & locally operated general construction / remodel company with over 60 combined years in the industry. Although we are general contractors and can do everything, we specialize in kitchen and bathroom remodeling. We have found that through proper communication and great listening our customers are more at ease and comfortable from beginning to end. It is our pleasure to provide top service in design assistance, material decisions, planning, demo and project completion. We go out of our way to uniquely tailor our service to each of our customers needs, wants and desires. We realize our customers invite us into their homes to provide the best service possible and we don't stop until we have done our best to help our customers turn their dreams into a reality. Thank you kindly for taking the time to look into Johnson and Sons Construction, LLC. We look forward to the opportunity to serve!

"I reached out to Johnson & Sons and several other contractors to discuss the possibility of opening up and completely remodeling my kitchen and bathrooms, with the addition of a shower to the former half bath off the master suite. After receiving bids and meeting with each contractor, I went with Johnson & Sons due to the transparency and consideration Vic Johnson showed when discussing the project and its challenges, as well as providing a detailed quote. Because this remodel involved the removal of walls, tiling of the kitchen/bathrooms, potential size constraints, and a re-plumbing of the house, It was very important for me that things be done correctly, to code and with permits. Once demo and construction started, things proceeded at a brisk pace with minimal lag between subcontractors, and inspections. Their tile guy, Tony was great to work with and very helpful with making the appropriate detail selections around the showers. We did have a long wait for a cosmetic piece of cabinet siding, which ended up being the final part needed to complete the project. Vic was direct with me about the issue and the delay. Such a minor issue is in my opinion, very small potatoes compared to having quality work done. Ultimately, Johnson & Sons came in slightly under their contract price - a very pleasant and welcome surprise."

Install Boiler questions, answered by experts

If you have a closed-system boiler that needs an expansion tank to work, you cannot run your boiler without it (not without the risk of extensive damage and even explosions). Your options include moving the boiler to another spot, rerouting boiler piping to a more open area, or completing a remodel around the boiler to create more space for the tank.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
