"Hired Superb LLC to remove three thru the wall air conditioners, brick up opening on exterior and drywall interior opening. The interior drywall installation was very good. The brick installation on exterior wall was amateurish at best."

"Very Happy with choosing Golden Temple Builders for my construction needs. Nick the owner was very professional and clearly explained the stages of the project and was able to work with the pricing points that I could commit to. His team went above and beyond my expectations, and job was completed even well before promised. Would Highly Recommend!!!! 10/10"

"I don’t usually leave reviews but I had to write one for Rightway Construction. Great prices and even better customer service. They did our master bathroom and completely remodel our floors. We couldn’t be happier. I will re-hire them in a heart beat."

"J & H was phenomenal. Great price and an exceptional product. Replaced all kitchen countertops and installed new countertops on the bar. Could not be happier with the finished product. Answered all our questions and worked with us on customizing some items. Countertops and backsplashes all match patterns at the joints. Looks like one continuous piece. Highly recommend J & H."

Custom Home Builders FAQs, answered by experts

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?
