"Stag Construction was hired to replace poorly installed Hardi Board siding and replace patio doors and window. Pictures show after corrections of miscut siding, siding pattern not running in same direction, siding not even from panel to panel, wavy uneven fascia, 2"gaps between soffits and siding, roof edges straightened and more. Fascia is now straight and runs parallel to top of windows and no holes/gaps for rodents to enter. Amazing! Due to the unknown extent of the work, contract was" by the hour, not a bid. What a pleasant surprise to deal with a company that knows how to install so as not to void a warranty. Austin and his brothers were professional, knowledgeable about the product, courteous, and efficient. Work hours calculated accurately and materials receipts were detailed. I appreciated their willingness to discuss options and express opinions when asked. Stag Construction will be doing more work for me next spring. Looking forward to it!"

"Recently, we had Sage Decks build us quite a large Trex deck on the back of our house, George and Evan were really great to work with! They had our deck built in less than a week. We also had them put in lighting on the top area of the posts in the railing, and also on the steps. The deck turned out beautiful! We love our new deck! We would recommend Sage Decks to everyone! We give them 5 stars!"

"Fantastic. Had them improve and rebuild a porch out of Trex. They probably over-engineered the job at a competitive price. They got me in quickly and finished in two days. I can't tell you how rare it is for a contractor to keep commitments in Missoula. Easy to work with, would not hesitate to use them again or recommend."

"After we worked with ED Enterprises on our bathroom remodel we decided to hire them again to build our large shop. This proved to be an excellent choice! From start to finish they were easy to work with, communicative, professional, punctual, and thorough. They explained each part of the process with us and answered any and all questions we had. They communicated with us through each step so we knew what to expect, when they’d be here to do the work, and what would follow. We greatly appreciated how in the loop we felt through the process and how well done the work is. Our shop was very well built and we’re so happy with the final product! The entire experience with ED Enterprises was excellent and we will work with them again."

"Hello! I am a contractor in the Bitterroot Valley specializing in residential framing and exterior timber work. I have worked with Lasting Decks for a while now, and have been impressed with their quality and professional workmanship. Their friendly and knowledgeable personnel have been very helpful to myself and others I associate with, and I will continue to seek out their services. I can certainly recommend Lasting Decks, but only if you want things really well done so your deck will last... up to you, I suppose. 😁 Lyman Jessop, Highland Hills Builders LLC"

FAQs for deck or porch projects in Missoula, MT

Northern white cedar is the most affordable cedar decking type and delivers exceptional value with low material expenditures. This option provides proven cost efficiency, meets essential durability standards, and is easy to paint or stain to meet your aesthetic preferences. By comparison, eastern red and western red cedar supply extra longevity and richer texture for a modest increase in investment.

Yes, cedar is a great choice for decking material. It offers a timeless look and natural resistance to decay and insect damage. Keep in mind that cedar requires regular maintenance, like resealing and cleaning, to keep it in top shape. With proper care, a cedar deck can enhance the appeal and value of your outdoor space for years to come.

No, cedar is not pressure-treated because it contains oils and tannins that naturally resist insect damage, rot, and decay. With regular maintenance, including annual cleaning and resealing every two to three years, cedar maintains its structural integrity and pleasing appearance for 10 to 15 years or more. Cedar’s natural durability, without need for chemical treatments, makes it an environmentally friendly option for outdoor structures like decks.

You should stain or seal your cedar deck every two to three years to maintain its appearance and longevity. This helps protect the wood from moisture, mold, and environmental damage, preserving its natural color and extending its lifespan. Regular maintenance keeps your outdoor space both attractive and durable season after season.
