"Seddik and his crew did great work on my house addition. The constant communication and attention to detail made the evolution stress-free. We were able to move back in a week earlier than initially quoted and the final cost was within a few percent of the estimate, mostly due to additional touches we added on during the build.

"Eco Power Works did a great job on my kitchen and bathroom renovation ! Daryl and John were very patient listening to my ideas. They brought in an architect who was reasonably priced and made suggestions to overall designs which I am so glad they did ! The project from Start to finish was on schedule which O was pleasantly surprised - these guys kept their words and their workers were always on time respectful of my property and time. I like that they always checked with me when they took major steps to double check that everyone was on the same page - they communicated every step of the way and were very careful to to do the job right. I really love the beautiful cabinets and marble countertops which were my dreams. I am so glad I hired these guys - they really did a great job overall - will definitely recommend them to my friends and neighbors !"

"I hired RLD Builders to construct a retaining wall that needed replaced before we could repave the driveway. RLD Builders came in with a competitive price and won the job. What was to take a few weeks turned into a three month ordeal. The county permit process caused hurdle after hurdle to get the permits but Rafe kept on the county and we finally got the permits and the job was completed to our satisfaction. We then put the house on the market for sale and had moved to our new out-of-the-area location. The hot water tank in the basement decided to let loose causing major damage to the basement. This is where RLD Builders exceeded our expectations. Rafe and his crew jumped in and cleaned up the water damage, worked with the insurance agents to get approvals, and completely rebuilt our basement. Being that we were no longer in the area, it was a blessing to have RLD Builders on the job to take care of all the details. We couldn't have done it without them. GREAT CUSTOMER SERVICE ! ! !"

"Studio 76 completed my entire home remodeling for single-family home I bought in as-is condition. Home was in 1970 condition and nothing was updated over the years.

This project was very pleasant experience and I am very impressed with quality work performed by them. I definitely recommend them for any kind of project as they have capability and tools to complete any tasks."

"I signed a contract for work to be completed in 4 weeks. 4 Months later, work was finally (mostly) done - but only with extreme nagging on my part and excessive excuses and push back. The contractor only came to the project site if his sub-contractors created an issue (which was often). They dropped my A/C unit down a 10 foot hole, they didn't finish half the projects they said they would and completed the other half incorrectly based on hand drawings and gestures because neither the contractor or I could speak the same language as the sub-contractors, they made promises to show up and never did. Worst of all, they used design plans from a previous contractor that were approved by the city - but didn't use those plans and never updated the plans. The city inspector came and did not pass the project due to this discrepancy, but Vladimir told me it had passed. The city told me the permit expired. So - now Vladimir won't answer my emails and I have to pay someone else to fix it all."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
