"JBRS has zero post sale customer service and their products are cheap & grossly overpriced! I have been waiting for 3+ weeks for anyone to respond to an itemized Punchlist of issues after both a shower & a shower/tub replacement. Issues include: Lost water pressure, poor preforming Jacuzzi fixtures, drainage problems, shower pan no longer supported by subfloor (= bouncy feel), yellow stains left on cheap hollow plastic shelf brackets, grout lines in both bathrooms do not align, walls left out of plumb, marginal clean up, etc. Worst of all: No attempt to make contact after email & mailing attempts and filling multiple satisfaction surveys! Last week, I instructed the bank financing their 12 month no interest/no payment promotion to withhold the 50% balance still owed. Still no response! Unbelievable! Do Not Use Jacuzzi Bath Remodel of Seattle!"

Subcontractors questions, answered by experts

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.

A contract should outline the scope of work, timelines, costs, payment schedule, and materials used for clarity and protection.

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.

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.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.
