Siding and Trim

GemThane® Siding is a low-maintenance, pre-finished siding system that offers the warmth, charm and value-enhancing properties of real wood siding without the upkeep.

A siding for all seasons

Yearly freeze/thaw cycles can wreak havok on traditional painted wood siding. The coatings used for GemThane siding are classed as semi-permeable membranes. Water cannot readily penetrate but water vapour can pass through the film. Thus, the moisture content of the wood changes slowly with the seasons but it will not become saturated in wet weather nor parched during dry spells.

The latex paints used on other sidings are quite porous, so dramatic swings in water content occur; this permits bacterial growth, makes the wood susceptible to freeze/thaw damage and encourages cracking and splintering.


Premium product, affordable price

Compared to painting on site, pre-finished wood siding is the hands-down winner. The over-the counter price of raw wood is low but the on-site costs are astronomical at today’s labour rates. When all is said and done, pre-finished siding costs less and speeds up your project.

Lower installed cost

Which brand of pre-finished wood siding offers the best value? Don’t be misled by the over-the-counter price. Sure, GemThane Performance Plus Siding sells for more because it’s a vastly better product. But it has the lowest installation costs in the industry, which means that the overall cost to the homeowner is never higher, often less. At the end of the day, the superior wood, the marine-grade coating and the lifetime warranty built into GemThane Siding are free bonuses. That’s the GemThane value proposition.

In any case where the building is going to be strapped anyways, or if you are re-siding an existing building, we offer the “Value Plus” version of GemThane pre-finished siding. This alternative version has a limited coating on the reverse side, which only covers overlapping areas. Foot-for-foot, it costs about the same as ordinary paint-based sidings. The coating on the front of the siding is the same, whether you choose Value Plus or Performance Plus.

Deck Building

We Build All Year Round

The most important part of any deck project is finding the right builder to do the work. Our builders have the right set of skills, our designers share your vision, and we always can adjust project according your price range

Deck Foundation

Helical Piles - Every good thing begins with a good foundation, and your deck is no different. Strength and stability is an important thing to build upon, and that’s why we like to build our decks upon something called Helical Piles. Often known as Screw Piles, Helical Piles are quickly becoming the most efficient and cost effective way to provide your project with a safe and sturdy foundation.

Deck Framing

Metal Framing - Once you have your post properly anchored and standing strong, it’s time for phase two: framing. Available in both metal and traditional pressure treated lumber, framing is the skeleton that supports you decking for the duration of its life.


Low Maintenance Materials - After your foundation is set and your framing secure, it’s time for the main event of the building process: your decking of choice. This can take on many forms, from traditional pressure treated to synthetic materials (composite/pvc), but is always accompanied by one constant; experienced and skilled build teams.

Deck Accents/Details

Having a new deck is great, but what really turns you backyard space from renovation to staycation are the character pieces and accents that you choose. Things such as custom pergolas, privacy screens, shading options and custom metal artwork can go a long way in turning your outdoor space into a retreat; and we all want the kind of yard that will leave our neighbors and friends jealous and talking.
