Alaska Power Vac LLC
Alaska Power Vac LLC
Locally owned & operated by Curtis & Anita Leader.
"We were very impressed with this business; the owner's wife answered my call and courteously and professionally arranged a relatively large job/cleaning within a week. The owner himself with his associate came out and performed the job, graciously adding on a full HVAC cleaning to the prescheduled air duct and dryer vent cleaning which extended his day quite a bit. He did a lot of education and they did a courtesy seal up as our air duct air intake had been drawing in air from a crawl space that had not been properly sealed. I don't think the air ducts had ever been cleaned in our recently purchased home (built in 1998) so everything was in significant need of cleaning, and we are so pleased we did this - the air was noticeably fresher, the ducts are no longer delivering fine dust (we were told quite a bit of remodel dust was still in the ducts from a 2012 remodel), and everything should be running more efficiently. Highly recommend investing in this particularly for any new home owners."

"4 years later - still vacuuming up material from the duct sealing. While the report showed they had sealed the ducts, the improper and inadequate installation was so poor. Total waste of money paid to this contractor. Ducts not cleaned beforehand. Left Untrained and unsupervised staff to do the work. Material did not stay in the ducts. Home damaged. Work done in 2017. Vapor barrier work was okay but again damage while doing the work. Hopefully this company has learned how to do the work properly since 2017."

"The work of Mason Siding transformed our condo building from looking like a rundown tenement into a prime beachside property. Dave Mason worked with us for almost a year from making his first informational and impressive presentation through several pre-work visits, installation visits, and end of project inspection. Work began in a timely fashion and the crew was as enthusiastic, informed, and skilled in their work as Mr. Mason. They were professional, flexible, and easy to work with. They answered all of our questions, explained the process, and made adjustments as necessary. All of the owners in the condo love the look and quality of our new Everlast Siding. I highly recommended Mason Siding and Supply for your siding work. They will keep you smiling.

Makari Construction LLC
Makari Construction LLC
At Makari Construction we believe that producing quality work, with financial transparency is the key to a successful contracting company. Unlike many contracting companies, bids and invoices are itemized with labor hours and material receipts so the customer can see where their money was contributed to the completion of a project. And if there is an opportunity to save finances on a budget, those savings are directly reflected on the customers invoice, rather than the contractor keeping that extra profit. We can perform any function from a simple honey-do list, to full remodels and additions. By building our foundation on honesty and transparency, we build stronger relationships with our customers.

We will show before and after pictures of past projects and discuss basic costs and fees for design work, building permits and so on. We will take some basic measurements and a few digital pictures of the project location. The first meeting usually takes about 1 hour. With this information we can prepare a preliminary estimate.
