FAQ

Estimating painting costs depends on room size, surface condition (how much prep work is needed), paint quality, and number of coats. A small room might cost less, while larger homes or exteriors cost more. Instead of dealing with guessing and surprise expenses, Grand Montréal Renovation offers free, transparent quotes so you know exactly what you’ll pay — no hidden fees and high quality guaranteed. 

Different paints are formulated for different conditions. Outdoors, you want products that resist moisture, UV rays, and temperature changes. Indoors, the priority is durability and easy cleaning in high-traffic rooms like kitchens or kids’ rooms. At GMR, we stock and apply high-grade paints suited for Québec’s weather, ensuring long‐lasting results that look great both inside and out.

In most cases, two coats of finish paint plus primer (if needed) are essential for a solid, even finish — especially when covering dark colours or painting over rough or stained surfaces. Skipping coats can lead to uneven colour, patchiness, and faster wear. Our team at Grand Montréal Renovation calculates exactly how many coats your project needs so your paint job looks flawless and holds up for years.

Matte finishes help hide imperfections but are harder to clean; satin or semi-gloss finishes offer more durability and shine, which are excellent for trim, kitchens, and bathrooms. The right finish depends on room use and your aesthetic preferences. GMR helps you choose the optimal finish for each space so you get the balance of beauty and functionality.

Exterior painting works best in late spring, summer, and early fall when temperatures are moderate (not too cold, not too hot), and humidity is low. Doing exterior work in winter or on very humid, hot or freezing days can result in poor adhesion, cracking, or peeling. At Grand Montréal Renovation, we plan outdoor paint jobs around optimal weather windows so your exteriors look great and last longer.
