Question 1

How often should I repaint the exterior of a wood-sided home in New Brunswick?

Accepted Answer

Most wood-sided homes in New Brunswick need exterior repainting every 7 to 12 years, though homes in coastal areas or those with older, thinner paint coats may need it every 5 to 7 years. The wide range comes down to paint quality, surface preparation from the last job, and how much punishment your specific home takes from the Maritime climate.

NB's climate is genuinely hard on exterior paint. You get the full package: salt-laden humidity off the Bay of Fundy and the Gulf of St. Lawrence, inten

Question 2

What is the best way to repair and repaint water-damaged drywall in a New Brunswick home?

Accepted Answer

Water-damaged drywall needs to be fully dry and structurally sound before you touch any paint — the most common and costly mistake homeowners make is painting over a repaired area before the underlying drywall has completely dried out. In New Brunswick's humid climate, this drying process takes longer than most people expect.

The first step is always to find and fix the source of the water. Painting over water damage without addressing the cause is a waste of time and money — the damage will co

Question 3

How do I prevent mildew from growing on painted exterior surfaces in humid NB summers?

Accepted Answer

Mildew on exterior painted surfaces is one of the most common complaints from NB homeowners, and with good reason — the combination of Maritime humidity, shade from mature trees, and warm summers creates nearly ideal conditions for mildew and algae growth on siding, soffits, and trim. Prevention starts with the right paint choice and continues with regular maintenance.

Mildew is a living organism, and it grows wherever it finds moisture, organic material to feed on, and moderate temperatures. N

Question 4

How do I store leftover paint properly so it stays good for touch-ups in NB's climate?

Accepted Answer

Properly stored latex paint can last 10 years or more, but New Brunswick's climate — particularly the freeze-thaw cycles in unheated garages and basements — is the single biggest threat to leftover paint. The key rules are: keep it sealed, keep it from freezing, and keep it out of heat.

Latex paint is an emulsion — tiny polymer particles suspended in water — and it is destroyed by freezing. When latex paint freezes and thaws, the polymer particles clump together irreversibly. The paint looks lu

Question 5

When should I repaint my exterior trim versus my full house exterior in New Brunswick?

Accepted Answer

In New Brunswick’s climate, exterior trim almost always needs repainting before the main siding does — and targeting trim refresh on a 4-7 year cycle while repainting the full exterior every 8-12 years is a cost-effective strategy that prevents moisture damage.

Trim takes the hardest punishment of any exterior surface. Horizontal surfaces like window sills and door sills collect standing water during NB’s heavy spring rains. South- and west-facing trim gets intense UV exposure. Window frames ex

Question 6

How do I fix chalking paint on the exterior of my Saint John home near the coast?

Accepted Answer

Chalking is the powdery white residue that rubs off on your finger when you touch older exterior paint, and it is extremely common on coastal Saint John homes — the combination of Bay of Fundy salt air, UV exposure, and moisture accelerates the breakdown of paint binders that causes chalking. The fix is manageable, but skipping the removal step will cause your new paint to fail within a season.

Chalking happens because UV radiation and weathering break down the resin binders in exterior paint o

Question 7

How do I fix paint bubbling or blistering on exterior walls of my Fredericton home?

Accepted Answer

Paint bubbling and blistering on exterior walls is always a symptom of one of two things: moisture trapped behind the paint film, or paint applied in poor conditions that did not adhere properly. In Fredericton, the most common cause by far is moisture — and you need to find and eliminate the moisture source before any new paint will last.

When blisters appear on exterior paint, the paint film has lifted away from the substrate because moisture or vapour has pushed from behind. In older Frederi

Question 8

What causes paint to crack in an alligator pattern on exterior siding in New Brunswick?

Accepted Answer

Alligatoring — that distinctive cracked, scaly pattern that looks like reptile skin — is almost always caused by paint layers that have lost their flexibility and can no longer expand and contract with the substrate underneath. In New Brunswick, our climate practically guarantees this will happen eventually if the wrong paint was used or if layers were built up improperly over the years.

The physics of alligatoring are straightforward: wood siding expands and contracts with every change in temp

Question 9

How do I do a paint touch-up on a wall without it being visible in my Moncton home?

Accepted Answer

Invisible touch-ups are one of the trickiest things in residential painting, but with the right approach you can get very close to seamless. The key is matching not just the colour but the sheen level, the texture, and the application method — all three have to align for the touch-up to disappear.

Start with the paint itself. If you have leftover paint from the original job, stir it thoroughly before use — settled pigment and separation are common in stored cans, and using unsettled paint will

Question 10

What causes paint to turn yellow over time on white trim in New Brunswick homes?

Accepted Answer

White trim yellowing in New Brunswick homes is almost always caused by one of three things: oil-based alkyd paint oxidising with age, lack of sunlight exposure, or nicotine and cooking residue — and the fix depends entirely on which one you are dealing with.

Oil-based and alkyd paints were the standard trim finish for decades, and they are still found in huge numbers of pre-2000 homes across Fredericton, Saint John, and Moncton. Alkyd paint produces a beautiful, hard, smooth finish — but it con

Question 11

How do I clean painted walls without damaging the finish in my NB home?

Accepted Answer

The safest way to clean painted walls is to start gentle and only escalate if needed — a damp microfibre cloth handles most everyday dirt, while a diluted dish soap solution tackles grease and scuffs without damaging the finish.

The sheen of your paint is the most important factor here. Flat and matte finishes are the most delicate — they were not designed to be scrubbed, and even a damp cloth applied with too much pressure will burnish (polish) the surface, leaving a shiny spot that is impossi

Question 12

How long does interior paint last before I need to repaint rooms in my NB home?

Accepted Answer

With quality paint and proper preparation, interior walls in a New Brunswick home typically last 7-10 years before a full repaint is warranted — but high-traffic areas like hallways, kitchens, and bathrooms often need refreshing every 4-6 years, while low-traffic bedrooms can go 10-15 years without touching them. The range is wide because paint longevity depends far more on surface preparation, paint quality, and how much wear a room takes than on the paint brand alone.

The biggest factor in ho
