"I needed a custom porch built on my 1940s home. John and his team handled the project with creativity and sensitivity to the unique situation. Drawings and permits handled quickly, they even utilized bricks I had stored and extended our porch space to match the existing footprint"

"I had to have my entire bathroom torn out and replaced with new walls, new enclosure, tub and flooring. I am very happy with the job that Cobar Builders did in my home. They were all very friendly and updated me on their progress and asked me how I liked certain things done...honestly this is the first time I have ever hired a contractor to do work in my home and at first I was very nervous, but all my fears and worries have been allayed by Elvin, the owner, and his crew. Elvin and his team were always up front with me about any additional costs and was very responsive to my calls and texts. I definitely recommend them highly."

"I recently had the pleasure of working with an incredible team of contractors who undertook the task of fixing my popcorn ceiling. From start to finish, they demonstrated an unparalleled level of professionalism, expertise, and dedication, leaving me thoroughly impressed and completely satisfied with their work. I would like to share my positive experience with this outstanding crew and recommend them wholeheartedly. From the moment I contacted them, their customer service was exceptional. They were responsive, attentive, and took the time to understand my requirements and concerns. They patiently answered all my questions, providing detailed explanations of the process, materials used, and timeline involved. Their clear communication and transparency instilled confidence in me right from the beginning. When it came to the execution of the project, the contractors truly excelled. They arrived promptly and were well-prepared with all the necessary tools and equipment. Throughout the entire process, they demonstrated an incredible level of skill and craftsmanship. It was evident that they were highly experienced in working with popcorn ceilings, as they navigated the intricate textures and patterns with precision and finesse. Not only were the contractors technically proficient, but they also displayed a strong attention to detail. They ensured that every inch of the ceiling was meticulously repaired, leaving no traces of imperfections. The final result was nothing short of remarkable! My popcorn ceiling was transformed into a smooth, flawless surface that looked brand new. I could not be happier with the outcome. Furthermore, the contractors maintained a clean and organized workspace throughout the project. They took great care to protect my furniture, floors, and belongings from any dust or debris. After completing the repairs, they diligently cleaned up the area, leaving my home in pristine condition. Beyond their exceptional workmanship, the contractors exhibited a genuine commitment to customer satisfaction. They consistently checked in with me to ensure that I was pleased with the progress and final result. They went above and beyond to accommodate any additional requests or adjustments I had, working tirelessly to deliver a finished product that exceeded my expectations. In conclusion, I wholeheartedly recommend the contractors who fixed my popcorn ceiling. Their professionalism, expertise, attention to detail, and commitment to customer satisfaction are truly commendable. If you are in need of skilled contractors who can transform your popcorn ceiling into a flawless work of art, look no further. These contractors are the epitome of excellence, and I am incredibly grateful to have had the opportunity to work with them."

"Ask to work with Rafael, if you're in Seattle, he's a true professional. He takes pride in the relationship he builds with his customers and has a team that is meticulous and extremely fast. They came in and painted the exterior of my home and the quality of the team's service was nothing short of outstanding."

"Spectrum One is our choice over and over again for renovating our home, which was built in the 1960s. Dennis comes out and looks at the scope of the project and gets back to you in a timely manner with an incredibly detailed and professional proposal. He takes into account your vision for the home and offers suggestions for improving the project or explains how the team can make that vision come to life. The project managers who oversee the project from start to finish have been diligent, respectful and ensure that the work being done is of the highest standards. They are on-site every day with a whole team working to get the job done as beautifully and as quickly as possible. The attention to detail from the whole group is what I most appreciate. We have used them for whole-home flooring (removal, installation and baseboards), recessed lighting, countertops, backsplash and would trust them with any project. We recently completed a third project with Spectrum One that included widening doorways, redoing an outdated fireplace hearth, and remodeling two bathrooms. Everyone at Spectrum One is quick to respond, honest, creative, and fun to be around. We love them and highly recommend to anyone looking to do a renovation, repair, or build!"

Custom Home Builders FAQs, answered by experts

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

Builder-grade is one of two types of stock cabinets, whereas semi-custom designs allow homeowners some control over the color, finish, or hardware on their cabinets. Stock cabinets are sold in construction-grade and builder-grade designs. Construction-grade cabinets are usually made from inexpensive medium-density fiberboard, which is prone to moisture damage, whereas builder-grade models are a step up with higher-quality materials. Construction-grade designs are the most common type of cabinets in America.

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.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.
