Need Interior Renovations?

We respect your home.


1 : to restore to a former better state (as by cleaning, repairing, or rebuilding) 2 : to restore to life, vigor, or activity (Webster's Dictionary)

We offer savings on quality hardwood flooring because we buy directly from a wholesaler.  With no retail store overheads or sales commissions to pay, we can pass these savings directly to you.

Savings on quality hardwood flooring


Attic 1

Before: This was an old house with no insulation. The attic was dingy, filled with "junk" and unlit.

Attic 2

We cleaned it out, added framing for walls, insulation and installed a proper vapor barrier.

Need more living space?  

Homeowners can get more living space by having an attic or basement finished.  We take the headaches out of renovations for you whether it is an attic, basement, new kitchen, bathroom, flooring, walls, doors or complete top to bottom home renovation.  

The top four pictures show the progression of one of our attic renovations.  Here, we insulated the roof and converted an old attic into a new master bedroom with ensuite bath.

Respecting your home

We respect your home and do our best to minimize the dirt, dust and inconvenience.  We put up dust barriers when needed and clean up the jobsite daily.  A renovation usually requires removal of the old and installation of the new.  Getting the old stuff out and moving the new building materials in is done with care and caution.  Once the refuse is out of your house, we arrange to take it to recycling or the dump.


We don't cut corners.  We show up as promised, we keep a tidy jobsite  and  always  strive to do the job right.  That is our Integrity Commitment to you.


People sometimes try to save money by doing it themselves.  That is not a bad thing, but it is important to know what you are doing.  We often end up fixing do-it-yourselfers' errors or other contractors' mistakes.

Savings on quality hardwood flooring

We can install the hardwood floor you buy somewhere else or you can get your hardwood flooring directly from us. We have a special arrangement with a hardwood flooring wholesaler.  There is no retail middleman, which is why we can offer big savings over what you can typically buy from a flooring retail store. 

The difference between cheap and quality hardwood flooring

Where the wood comes from can make the difference.  Our quality hardwood flooring comes from within 500 kilometres of here where the logging is regulated and trees are planted to preserve our forests.  Forests are sustained and transportation costs are minimized.

Each growing season produces a ring on a tree.  Our short growing season produces trees with tighter rings. This makes the wood harder.  Cheaper hardwoods from places such as China are often harvested by clear cutting subtropical forests. The subtropical trees have a longer growing season and larger rings. They produce softer wood even though they may be the same type of tree.  

Unregulated logging practices can destroy forests completely and we have found the softer wood is much more susceptible to marring and scratching.
