He gave us a flat price and stuck to it. He was also one of the fastest of bidders. We contacted him fairly late in the selection process, and he got his numbers in while one of the first companies we had contacted was asking for more time. His crews worked quickly and efficiently. The one near-crisis was that, due to a mix-up (might have been ours or theirs) I discovered ten minutes before the first panel of siding was to go up that we had the wrong material. We wanted unpatterned siding, and what we had was faux wood-grain. While we were paused to get sorted out, we also decided to go with a different, darker color. In spite of the problem, the crew only lost about half a day, and by rescheduling the order of work a bit, we stayed very close to on time. Just before the work started, while working on another project, we discovered some long-hidden old termite damage. A termite inspector confirmed it was old and inactive. (I think it dates to before our purchase of the house in 1997.) We alerted Zak to the problem. He brought in a subcontractor who evaluated the problem, and coordinated with Zak's crew to do the repairs in a prompt and professional manner, sliding in four new joists to sister in next to the damaged wood, and repairing the exterior wood as well. This was work far outside the job we had hired Zak to do, and he quite fairly charged us extra for it -- but his subcontractor got it done quickly and well, at a reasonable price and in a way that did not interfere with main project. It was very useful and important to have me (the home-owner) on site during the work, in order to make sure that various details (checking the siding material, positioning a decorative band-board, adding a bathroom vent exhaust we'll need pre-installed for a future project, etc.) got done as desired. The team worked fast, and it was a lot more efficient to make sure things gone done the way we wanted the first time, rather than asking for changes after the fact. Just checking up on progress every now and then was very useful. Our house is no longer drafty, and holds temperature much better. The house is also much quieter, with street noise far less noticeable. The old siding was at the point where we were risking water intrusion and substantial damage to the main structure of the house. Now we should be good for at least several more decades. We would certainly tell friends and neighbors to go with Zak and Alco. In fact, we've already signed up with them to do some additional window work.

Did not use. The saleman was a little too pushy in trying to get contact signed. And, after having a professional structural engineer evaluate the problem I realized I needed to get bids from a couple other companies.

Structural Engineering questions, answered by experts
Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys.
Some of the warning signs that structural engineers check for include:
Sagging, shifting, or damaged walls, ceilings, or roofing support
Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.
The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.
A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection.
On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.
