Covered front porch and deck stair restain in Bowmanville, Clarington

A covered porch on the edge of Bowmanville

Clarington is really several communities, and Bowmanville, its largest centre, has grown outward with new subdivisions around its older heritage core. This house sits in one of those newer areas: a two-storey home with beige siding, a stone-clad base, and a deep covered front porch sheltering a stained wood front door. The porch has a wood floor and a short run of wood steps down to the walk, wood-wrapped posts on stone bases, and a tongue-and-groove pine ceiling. Out back, a deck drops to the yard on a stair that runs along a white vinyl fence.

The owners asked us to refinish the porch floor, steps, posts and ceiling, and to restain the back stair treads. The front door itself was in good condition and stayed as it was, which meant the porch colours had to work with it.

What winter had done to the porch

A covered porch avoids most of the rain, but not the winter. The roof keeps off snowfall, yet wind still drives snow onto the front edge, and every storm means shovelling the steps and putting down ice melt. After several winters, the porch showed it:

• The original semi-transparent stain was worn to bare wood in a path from the steps to the door, and the step noses were scuffed and splintered from metal shovel edges.
• Rock salt had left the boards near the steps pale, dry and slightly furry, with white residue in the gaps between them.
• Dark rings marked the floor where planters had sat for a whole season, the result of trapped water and iron from a metal plant stand reacting with the wood.
• The ceiling was sound except along the front edge, where wind-blown rain had faded and water-spotted the first few boards.
• The posts had small gaps where their wood wraps met the porch floor.

The tricky part was the stone base. Natural and cast stone are porous, and stain that lands on them soaks in and is very hard to remove. Every board along the porch edge and every step meets that stone.

Getting the porch and stair ready

Protection

1. Planters, the bench and the mat were moved out to the driveway, and the front door was covered with plastic and tape so no cleaner or stain could reach its finish.
2. Where the porch floor and steps meet the stone, we masked the stone with a wide band of tape and plastic, pressed tight into the joints, then laid cloths over the stone below as a second line of defence.
3. Siding next to the porch and the vinyl fence by the back stair were covered with plastic sheeting.
4. The garden bed beside the steps was covered with breathable cloths.

Cleaning and correcting the wood

1. The floor, steps and stair treads were scrubbed with a wood cleaner and rinsed at low pressure, which also flushed out the salt residue from between the boards. Salt left in the wood keeps drawing in moisture and can stop a new finish from bonding.
2. The planter rings and the pale, salt-burned areas were treated with an oxalic acid brightener, which removes the iron staining and evens out the colour. Most rings disappeared; the faintest traces that remained would be hidden by the new finish.
3. The scuffed and splintered step noses were sanded smooth with a random-orbit sander, and their corners slightly eased so shovels would not catch them as easily.
4. The weathered front boards of the ceiling were washed gently from a ladder, rinsed with a sponge rather than a sprayer to keep water out of the light fixture boxes, and lightly hand-sanded.
5. Gaps at the post wraps were sealed with an exterior caulk.
6. Everything was left to dry, and we confirmed with a moisture tester that the floor and steps were dry right through before any finish.

A different finish for each part

Porch floor and steps: solid stain

Solid stain often fails on open decks, because water sits on the boards and lifts the film. A covered porch floor is a different situation: little standing water, far less sun, and mainly foot traffic to deal with. Here the owners wanted to hide the faint ring marks and the uneven, salt-bleached patches, which a semi-transparent stain would have shown. So we used an exterior acrylic solid stain made for decks and porches, in a warm mid-brown. It was brushed on two boards at a time along their full length, worked well into the board edges and end grain, and given two coats with the recoat time on the can respected in between. A fine anti-slip grit went into the second coat on the steps.

Posts

The posts were left to show their grain: two coats of a semi-transparent oil-based stain in a cedar tone a shade lighter than the floor, which ties them to the pine ceiling above and stands out against the beige siding and the stone bases.

Tongue-⁠and-⁠groove ceiling

The ceiling was never meant to look solid, so it got two coats of a semi-transparent stain in a lighter golden tone, applied with a brush working along each board. The fresh coats blended the faded front boards back into the rest of the ceiling, and the lighter colour keeps the porch from feeling dark.

Back stair treads: back to semi-⁠transparent

Unlike the porch, the back stair is fully exposed. Rain and snow sit on its treads, so a solid film there would be likely to peel. We used two coats of a semi-transparent oil-based stain in a tone close to the porch brown, so the front and back look related without being forced to match.

Choosing colours next to a stained door

The front door already had a rich wood finish, and the owners did not want the porch floor to compete with it. For the free colour consultation, sample stains went onto spare boards, which we stood on the porch beside the door and against the stone. In the morning the porch is in shade, and in the late afternoon the low sun reaches under the roof, so we looked at the samples both ways. A brown close to the door’s colour made the two blur together, and a grey looked cold against the beige siding and warm stone. A slightly darker, warmer brown than the door set it off while picking up the browns in the stone.

Leaving the entrance usable

The porch is the main way into the house, so we roped off only the area being worked on and kept the garage entrance free for the family. Each day ended with the tools out of the way, the steps swept, the stone checked for any spatter, and used rags dried flat and stored in a sealed metal can. The planters went back only once the floor had cured enough for weight, on small feet to keep air under them.

Looking after the porch through freeze-⁠thaw winters

• Use a plastic shovel or one with a rubber edge on the porch and steps; metal edges strip stain at the step noses first.
• Avoid rock salt on wood. Sand gives grip without drying out the boards, and some ice melts are gentler on wood finishes; check the label.
• Keep planters on small feet or a slatted stand, never directly on the boards, to stop new rings forming.
• Sweep and rinse the porch in spring to clear winter grit and salt.
• The steps will need a touch-up of solid stain first. We left a labelled can of each finish, marked for porch, ceiling and back stair.

Why this approach suits Clarington homes

From Courtice to Newcastle, houses here face freeze-thaw winters, and a front porch is where snow, shovels and salt all meet the wood. Matching the finish to each part of the house, solid where it is sheltered, penetrating where water sits, is the core of how our porch, deck and fence staining is planned. Since 2010 we have carried out painting and staining for households in Toronto and around the GTA, many of them in Durham Region, and our Clarington painting page covers heritage homes, new subdivisions and farm properties.
