"Kyle and his crew were great to work with and we are really happy with our new decks! They were all communicative, polite, hard working, and trustworthy. Their bid was very competitive and they stuck with the estimate with no surprises. I would highly recommend working with them!"

"Little Roofing's crew was excellent.  They were careful to keep our dogs inside the fence, left no rubble anywhere, and completed a very steep, difficult roofing job in less than ideal weather.  They let me know if there were going to be workers at my home on any weekend days, or if workers would not come when I might expect them."

"Tore out old deck and replaced with trex floor, steel skirting, and steel railing. Excellent work. So much so that we've hired 6 Point to replace the porch (deck) at ourfront door when the weather gets warm enough."

"In a previous review I stated I had not heard anything from the company about necessary repairs. That WAS NOT an issue with the company or its owner! It was an issue with electronic communications failure on my equipment. That issue is resolved (I hope!) I would highly recommend this company to anyone needing any type of repair for their home."

FAQs for deck or porch projects in Helena, 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.
