You've probably landed here looking for information about cornice mouldings and how to repair them. Knowing that this information isn't always easy to find, we asked one of our contractors, Felix Deblois-Beaucage, to tell us more about this type of renovation project.
Every project is different. For the project we are currently completing, we had to remove the old paint first. This created big holes in the wood because at least 1/4 inch of paint was removed. Next, we filled in the holes with putty- a very strong filler also used to fill in holes on cars. For wood knots, we used shellac- a resin- to seal them.
Afterwards, we sanded the whole surface to even it out. A water-based primer was then used to cover everything and create a nice base for the new coat of paint. Once the primer had dried, we applied 2 coats of water-based paint. It was almost the same colour as the old paint.
For the stucco (also called roughcast) of this cornice, we scraped its' surface and repainted it in the same colour.
It depends on the client. In certain cases, I’ve been asked to paint cornices using very bright colours like red or sky blue. Those types of colours often require up to three coats to look good.
It usually takes more time and work for bright colours. If you want to change the colour of your cornice moulding, for instance from a dark colour to a pale one, you’ll need a good primer to decrease the number of finishing coats needed for the pale paint to come across well.

It depends on the type of cornice you have. For this project, due to bad weather, it took us one week – because of the rain, we weren't able to work for a few days. If the weather had been perfect, it could have taken us less than 3 days! Also, this cornice needed a lot of repairs, which takes more time. If we only had to paint, it would have taken even less time.
The weather is a major problem because you can’t paint when it’s too humid or too hot. Unfortunately, paint doesn’t adhere well when the temperature soars above 35°C. Plus. it's hard on the workers to paint in these conditions.
Therefore, make sure you have at least 2 days of good weather after the renovation before you start the project. If it rains before the end of the drying time, the paint will drip and you’ll have to do it again.
Therefore, if you want a nice and durable finish, make sure the weather forecast is good before you start the job. Another challenge is height. Since cornices are high, we need tools that are made specifically for working at heights, like ladders and scaffolds.
It can be very dangerous and requires experimented workers that are used to working at heights. They also have to move ladders frequently to reach every part of the cornice moulding.
Again, it depends on many factors, like the type of roof, the cornice, the amount of prep work… For this project, since we had a lot of repairs to do and we also had to cut in the edges – between the beige stucco and the brown cornice- the price reflected the amount of work we had to do. If we only had to repaint the cornice, it would have been a lot cheaper.
But this is rarely the case for cornice mouldings; you almost always have to repair something. It can cost anywhere between $800 and over $10 000. For this cornice, the total price was $2000. Keep in mind that this kind of task is done at heights so it will always be more expensive than painting at ground level.
Since the weather can get so cold in Canada, I would say the best time is the beginning of the summer, in June. But in reality, most people do it in mid-summer. Contractors tend to be more available at that time of the year. In the early summer, we take care of other tasks such as patios and we don’t have the time to renovate cornice mouldings. In wintertime, this type of renovation project is impossible.
From the get-go, the renovation of a heritage building must respect certain rules. If your home has this unique status, some restrictions will frame any changes you can make to the cornice. Essentially, you will have to respect the original style of it and avoid the use of synthetic materials.
Due to the thoroughness required to renovate a cornice adorning a heritage building, it is best to hire a professional to do so. The latter will be able to restore your old cornice so that it gets as close as possible to its original version. If the cornice is in an advanced state of decomposition, the expert responsible for the work will sometimes use old photos to create a cornice whose style is in line with that of the house.
