"We had S&J install a new mini-split ductless system on a floor that we couldn't get cool. We also had them analyze our current system in our townhouse, which required an upgraded cold air return duct due to a bad design by the builders. Mitch was our representative, and he did a fantastic job analyzing what we needed. Mitch provided a better, more effective solution than we had heard from any of the other vendors. Additionally, he got us a great price (after rebates) on a system that was better than the other systems we had been previously quoted. The mini-split installation was a challenge, but the installers did a great job. They took their time to create an installation that looks and operates great! The cold air return duct upgrade brought our system static pressure from 0.75 inH2O down to 0.5 inH2O total, which is nearly perfect. Our air handler is running quieter now, and we are getting more airflow through our system. I would give Sanders & Johnson 10 stars if I could!"

"Had maintenance contract with Absolute to service HVAC, electrical, plumbing twice a year. On recent maintenance visit A/C condensation line was found to be clogged due to "dirt getting into the system from lack of filter maintenance". Cost $329 to clean line which was not covered under contract (and seems a bit excessive!!). Was told filter replacement was not covered in maintenance contract. Seems to me that this would be a priority maintenance item! Technician comment on last visit 5 months earlier stated filter was "still clean" and not replaced. Needless to say we will be finding another company to do our maintenance from now on."

Subcontractors questions, answered by experts

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

No, builders and general contractors don’t expect tips. In fact, some companies may prohibit their employees from accepting client tips. If you want to show gratitude for a job well done, consider writing a review of your builder or contractor or agreeing to be a reference for potential new customers.

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.
