"The man I talked to was very professional and timely. However, he explained that this particular job was beyond the scope of what their company does. I would certainly use them on another 'issue'.

"Once I sent her all the measurements, it took her a little while to get the options back to me.  Overall, they're good designs.  However, they're very simplistic and give general ideas for space planning.  I was hoping to have a better idea for sizes of furniture for the space and some variations on staging.  
Jill was very responsive when I did have a question.  I'm not sure how helpful it is to have a virtual design done.  If we lived in similar cities, I'd probably use her again for help with additional designs.

"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.

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

"It was good. They were conscientious. They kept us informed on what was going on. They placed a sheet and they cleaned out every night whenever they were finished. Their preparation and completion of the work was clean."

FAQs for addition to existing structure building service projects in La Grande, 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.
