"Dereck was professional, knowledgeable and really listened to what I wanted. Very kind and really knows what hes doing. He put in a patio, fence, fire pit, shed, lawn, gutters and some indoor projects. I will only hire him for any outdoor or indoor projects in the future! So happy with the work he did!"

"They did a fantastic job building the deck I've always wanted. I told them what I needed, and they completed the project perfectly, even in the rain! I would hire them again in a heartbeat. Very professional and personal at the same time. Woo-Hoo!!!"

"Only thing they did themselves was the patio ceiling & French drain for my project. Acted as hiring contractor for all the other work. Overall project was a success, but I didn't appreciate how the lead crewman/ owner spoke to his employee. Subcontractors that were hired were excellent."

"NW Builders & Renovation is the best that Portland has to offer. Tops in professionalism is Max, who was our point man for the roof project. He uses only the best materials, top of the line building and roofing materials make our job one that will last for a lifetime. I have confidence in Max, he was always there for any questions I had and when I had an unexpected disaster - a ceiling fell on me, he was right there, offering to come to my house and help me, in my hour of need, he was there. He finished the job with time to spare, and they did a thorough, excellent job. Now I have no fear of rainstorms making my roof leak, I can confidently decorate my home and know that the roof won't leak or fall in. Not only did they do a thorough and excellent job, they cleaned up all the mess that was left over after finishing. If I had to do it all over again, I would definitely choose NW Buildlers & Renovation and Max. my favorite go to roofing guy."

"Eventually, most people realize that while DIY can be fulfilling, the results are not always the greatest. Iâ ve built several decks in the past and was relatively happy with the work I did but I always noticed the little things that werenâ t â perfectâ . When we decided to add a deck to the back of our home I was ready to tackle the project myself when I realized Iâ m 1 - NOT 30 anymore and 2 - really didnâ t want to end up with something that lookedâ ¦ not what my wife and I wanted. With that in mind, I began the search for a contractor, which anyone in the market knows is a difficult task to find someone who is available in the next 27 years ;-). With the help of a couple of search engines, I found Mike and MG Exterior Contracting. Once I met Mike in person, I knew he was the guy to build our deck. He answered all of my questions, explained why some of my ideas, while possible, were not necessarily cost effective or attractive. We had planned on scheduling for later in the summer but a cancelation allowed us to accelerate our timeline. MG Exterior has what I believe to be a great way of getting materials for their projects- Mike orders needed material, then I called to pay for it. In other words, MG Contracting isnâ t padding the cost of materials or hiding extra profit under a â miscellaneous materialsâ heading Mike, John and Andy showed up on Monday morning on time and ready to get started. The material had been delivered the previous Friday, so they got started without delay. Any project is going to have issues that arise and our deck was no different but Mike made sure I was aware of all issues so there werenâ t any surprises when they we done. A little about the construction. MG Exterior Contracting uses a product I had not seen before, Trex tape. They taped the top of every joist and even the cut ends of the 4x8 that hold the deck up. Something I noticed after they were done is that the tape means when you look down, you donâ t see black Trex clips and bare wood. The tape basically makes the clips disappear. I could go on and on about how impressed my wife and I with both our new deck and John and Andy and Mike as people and workers but Iâ ll leave you with this, if I had to build another deck tomorrow, there is no other contractor I would call to have do the work. Cheers"

FAQs for addition to existing structure building service projects in Astoria, OR

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.
