Construction of a house extension story addition in Montreal

A general contractor for the construction of a house extension

You can put your trust into a general contractor of the House Extension Montreal group which includes several licensed and experienced general contractors as well as construction professionals over a wide area around Montreal.

Building and adding a floor to one’s house is a major project that requires an RBQ licensed general contractor, experience and resources to do the work quickly in order to remove the existing roof, build a complete floor and return the roof without exposing the house to the elements.

The construction of a house extension requires well-made plans in function of the customer’s tastes but also in terms of the budget. Too many people make plans and then request an estimate. With House Extension Montreal a draughtsman works under the supervision of a general contractor all throughout the design of the plans to ensure compliance with the construction budget for the extension.

Duration and cost of construction of a house extension

In general, one foresees for an enlargement of a house extension of about 10ft x 20ft approximately 4 to 6 weeks of construction. Costs will vary greatly depending on whether it is necessary to build foundations and a basement or if one can use just one concrete slab on the soil. The slab on the soil is much more affordable and reduces construction time. The elements that most influence the price of the construction of a house extension attached to the house are:

• the type of foundation (on slab surface or deep);
• the quantity and size of the windows;
• the type of insulation (rigid or sprayed with urethane);
• the outer coating (brick or lightweight such as Canexel).

Just a call and a visit to one of our construction experts will be enough to advise you and give you a price within your budget for your house extension project.
