"I rank Landson Construction #1 in the list of contractors we have hired in our 40 years of home ownership. Ari and his team of subcontractors recently completed a challenging remodel of one of our bathrooms--challenging because it is a very small area with limited space. Their finished job looks better than our separate remodel of a larger bathroom completed by one of the big firms that advertises daily on television. Examples: the tile work in our small shower is exceptional, and the vanity/oversized sink is a perfect match that does not dominate the small room. Ari Erickson (no relation to me) offered selections from his preferred vendors, but we had full latitude to shop on our own for all tile and fixtures. He and his subcontractors kept us fully apprised at all stages of the project, arrived promptly throughout the course of the work, responded promptly to our texts and emails, and cleaned up their work area at the end of each day. My highest recommendation: I always seek at least four bids for a major project, but I would forego that process and hire Landson Construction again for future building/remodeling projects, and would encourage friends and family to do the same."

"It wasn't timely. He hires cheap labor that does everything but isnt good at anything. The framers were hacks using broken lumber in spots. Sheetrock cracked and needed repair ( which they did) the new shower was installed without specialized mounting clips and the flange on shower walls were cracked. The shower door did not function and when I went to fix it, the hanging hardware fell off. New flooring throughout the house including the new addition. The new addition subfloor wasn't screwed correctly which resulted in a reinstall. In the old part of the house, the subfloor was not prepped properly causing the vinyl plank to bow and crack. Jim refused to fix. Jim's crew forgot to put a vent on roof so water came into house and collapsed the bathroom ceiling. ( He did take responsibility and fix that) overall very disappointed with someone that claims to do quality work. If I could rate lowerI would."

"We hired Enerjac to build an addition and kitchen remodel in October, 2024, and are still waiting for project completion in November, 2025. Far from having a "tradition of excellence," we found Enerjac to be deceitful, manipulative, and incompetent, with problems ranging from failure to contain lead dust to leaving holes in the exterior wall wide enough for a man to fit through in mid-winter. Communication was terrible, and our emails since mid-October, 2025, have gone unanswered, despite lingering issues like a non-functioning radiator and a cracked conrete stoop, both of which they installed. The project was plagued by delays and excuses. The structure was not built to the plan or specifications, for which we requested (and were denied) compensation. I would not recommend this company and do not plan to use their services again."

FAQs for addition to existing structure building service projects in Isanti, MN

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.
