"I recommend Dennis (Harmon & Harmon) in the strongest terms for a renovation, upgrade, or any other construction in your home. I hired Harmon & Harmon for some upgrades/repairs in a home I recently bought, including a major renovation of my attic (dark, unfinished space, bare studs) to be a fully finished room. Dennis saw the potential of the attic (which was huge & very open). Now fully finished, the attic has a beautiful composite wood-grain floor, finished walls, recessed lighting, full climate control with a mini-split, and he was even able to add a window with a view to the water. It is a huge room that now functions as a TV room for the kids with a big sectional couch, one corner is an extra closet/storage nook for my wife, & the gabled window area has table & chairs for reading and enjoying the view. Best thing about Dennis... 100% follow-through, 100% satisfaction. If I had an issue, he fixed it, period. Outstanding professionalism from start to finish. A+, 10/10!"

"Amazing service and great communications! If you are looking for an honest contractor who really cares for your property (and your money), then I highly recommend Promise Land. They renovated several properties for me in Centralia in the last 6 months, including a single family, a 100 year old apartment complex, and several storage units. Beth did a great job communicating the details of each project and in each case provided recommendations to save money or add more value to the property. She provided a high quality job with at reasonable cost and in a timely manner. Overall I was very happy with how the projects went and I look forward to work with Beth in the future."

"It went great. Andy was able to start quickly and fit us in. He installed drywall, soffit and flooring as well as doing some Painting for us. Would recommend him to anyone and hire him again if we have any future home remodel or handyman services."

"Yes! Eduardo and his son did a great job and I highly recommend them to anyone. There’s a lot of contractors who reached out about this project but what I really liked and one of the reason why I hired them because when Eduardo came out to look at the projects he listened and and then he shared with me his thoughts, unlike the others who just insisted this and that and I even almost kicked one out of the house already. After all, we the homeowners are the customers . Anyways, there’s more projects ahead of us and I definitely don’t mind having them to come out for estimate. We showed photos to friends and families and they all loved it."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Jon's work is as good as it gets! We have a rental property that we're preparing to put on the market. It needed a number of repair and update tasks completed, some small and some not-so-small. Everything from replacing siding to building a set of outside stairs to revamping a tile entryway to simply tightening some loose faucets. Jon has been ready, willing and more than able to meet every one of our requests, and his final work is exceptional. I wouldn't hesitate to hire him again, and will be calling on him for the "checklist" at our own home, too."

FAQs for addition to existing structure building service projects in Chehalis, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
