"I never contacted the provider or used this service in anyway. I have to
write this review so that the request to write this review stops
popping up.
The rating is bogus as it is required to be able to submit.

"We got three bids on this roofing project on our primary 1390 sq. ft. residence.  Two of our bidders were Angie's List recommendations. The third bidder wasn't but was highly recommended locally.  
John Jones, owner of Mid-Valley Building, was very professional and prompt.  He showed up when scheduled and was prepared. He responded promptly when we asked for modifications to his bid and gave us other options to consider.  We felt like we had selected a good team player when we signed our contract.  He asked for half at signing and the remainder at completion.  He was willing to take credit cards for payment which worked well for us.
John and his teammates showed up at 7:00AM and were done by 3:30PM.  John directed the roofing crew and his mother, Julie, did ground work cleanup. At the end of the day the roof was fully installed and the cleanup was perfect!
At the end of the day we asked for a new roof on our garden shed and John responded with a good bid and completed that add-on within a week.
All of his employees were pleasant and mindful or our property. We couldn't be happier and we highly recommend him and his crew! We will definitely use Mid-Valley Building again in the future.

"They did a good job. She had to submit like a photo but my daughter had them work on the central are of the loft. The deal was for one room. She got a lot of good ideal from her and it was worth it for her. They were professional and I did not hear anything negative."

"Let me start off with how amazing these guys are! They have worked with me every step of the way with payments and are very patient with my lack of being able to pay because of certain circumstances that happened. I make payments when I can and they are very flexible with everything! And my house was so clean when we came back i was pleasantly surprised! Thank you again for your hard work!"

"We weren't that happy with the results. It was a few years ago, and the surface is still pretty much intact. He had to use a primer and deck paint, rather than stain, and the primer showed through in several places as bright white marks against the dark brown stain. He left the extra paint so we could refinish where we wanted. We don't want or expect any follow up at this time. I understand that the deck needed a lot more work than the worker expected. So, my experience may not be a fair representation of this particular contractor.

"I have been using them for 3 years for multiple projects and would not go to somebody else. They also built a cabin in the woods. It was built 10 miles from the road so it was like carrying all the stuff up the path. They also did the garage and remodeling of the house, mostly kitchen and a little bit of plumbing work in the bathroom. I am still using them and I would be using them for the next thing that will be coming up too."

FAQs for addition to existing structure building service projects in Baker City, 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.
