"KN Remodeling redid my floors, removed a wall and got my JADU permitted, plus many more random fixes. Whatever project I threw at Nathan and his team he got done. They were great and I would use them again."

"They are very professional and their work is stunning. They bring your vision to life. Jose and his crew remodeled our whole downstairs our 3 bathrooms and kitchen. You need to see the transformation on his IG page! Unrecognizable! Even with the delays in material during COVID they stayed on top of it.

"Richard and his team were great to work with. The Team showed up everyday on time and even stayed later to avoid unnecessary delays. Richard made sure I got the kitchen I wanted, not what the trend is and encouraged to be differentâ ¦ I loved that! He made the whole project very easy for me. He took care of ALL the research, ordering, and delivery of all appliances, sink, and faucets, and all within my budget. His value added services that are included in his prices are â 5 Starâ . I truly appreciated the way he and his team handled things that I brought to their attention to be fixed or reworkedâ ¦ Richard wanted to ensure things were correct and looked good. Another very positive experience was working with the shop he partners with to supply the cabinets, countertops, and tiles. Maxine made the experience extremely painless. I wanted color and her recommendations were exact what I wanted! I LOVE THESE COLORS!! And the countertop is absolutely gorgeous! Thank you, Maxine!!! Now, regarding the quality, I gave a rating of 4 stars. The construction and assembly of the cabinetry, I would give 5 stars. The only constructive feedback I have is related to the little details. I feel the overall clean up after the project was done could have had more TLC. One suggestion is to have one full day focused on detailing and touch ups. The cleanup for this project was at the very end of a long day of super hard work, the guys were tired and the last thing anyone would want to do is cleanâ ¦ totally understandable. That said, I donâ t want this feedback to take overshadow the amazing job Richard and Team did! Thank you, 3-D Remodeling, for making my dream kitchen come to fruition â ¤ï¸ â ¤ï¸ â ¤ï¸ ."

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"Skyline converted our attached garage into a beautiful ADU with quality workmanship, fair pricing, and top notch materials. They were very particular with respect to details, which made a huge difference in the end. I would strongly recommend skyline and will use no other company for any project, large or small. If you want the job done right, with transparency and professional service from start to finish, look no further!"

"Was contacted directly by Phil quickly after submitting my info. He was at my house the next day. We had him transform our kitchen and bathrooms. He was very professional and prompt with communication. He worked with my wife on all the materials and textures and even finished 2 days earlier than quoted. Very happy with the services and will use Ramapo again!"

Subcontractors questions, answered by experts

Professionals optimize layouts, improve energy efficiency, and ensure structural safety and compliance.

Yes, professionals can offer design advice and material selections that complement existing architecture.

Pros provide detailed quotes and efficient management, reducing overspending risks on materials and labor.

The cost to draw house plans typically ranges from $800 to $2,700, with standard blueprints averaging around $1,800. For a custom home, the cost is higher, with blueprints often falling between $5,000 and $20,000, and potentially more for very complex designs. Several factors influence the total price, including the project's size, the number of rooms, the type of drawings required, and the architect's experience level. You may also need to pay a structural engineer to ensure building safety, particularly for custom homes.

You don’t have to commit to a complete home renovation to age in place comfortably—those can get pricey. Instead, focus on a few impactful changes. Consider adding a stair lift or installing ramps to eliminate barriers. Upgrading to non-slip flooring can prevent falls while adding brighter lighting can improve visibility throughout your home. These thoughtful updates can make your home much easier to navigate and enhance your comfort and safety without the stress and cost of a complete overhaul.
