Surface preparation
Filling cracks, holes and joints, sanding old paintwork, washing down greasy or dusty surfaces, and treating damp or mould stains before any primer or paint is applied.
Walls, ceilings, staircases and woodwork inside, render and joinery outside — cracks filled, surfaces sanded and primed before any topcoat is applied to the surface.
A good paint job in Aalst is decided before the roller touches the wall: filling cracks and holes, sanding old gloss, masking skirting and fittings, and choosing the right primer. Alpha Services prepares and paints interior walls, ceilings, staircases and woodwork, plus exterior render, cladding and joinery, matching the finish to the room or facade. Furniture and floors stay covered for the whole job, not just the first coat.
Filling cracks, holes and joints, sanding old paintwork, washing down greasy or dusty surfaces, and treating damp or mould stains before any primer or paint is applied.
Two-coat systems on walls and ceilings in the finish you choose, with cutting-in around skirting, coving and light fittings done by hand for a clean, straight edge.
Doors, skirting, architraves, banisters and staircases sanded, primed and painted or varnished, with attention to areas that see daily wear such as handrails and door edges.
Breathable masonry paint applied to render and pebbledash after cleaning and repairing hairline cracks, so the wall keeps shedding moisture rather than trapping it under the coating.
Window frames, fascias, gutters and railings rubbed down, treated for rust or rot where needed, and finished with a coating suited to being outdoors in a Belgian climate.
Floors, furniture, sockets and fittings covered and taped off before work starts, with dust sheets moved as the job progresses so the rest of the home stays usable.
Painting jobs in Aalst range from a fresh coat on one wall to a complete redecoration project. Render and pebbledash on exterior walls need a breathable masonry paint that lets the wall shed moisture rather than sealing it in. Alpha Services covers Affligem, Denderleeuw and Dendermonde for the same painting and decorating work. Cracks, holes and damp staining are treated before priming, so the paint is not asked to hide a problem underneath it.

A painter looks at wall and ceiling condition, checks for damp, cracking or old wallpaper, and discusses colours, finishes and which surfaces need extra preparation.
You receive a quote listing the rooms or elevations covered, the preparation included, and the paint system proposed, so you know exactly what is and is not part of the job.
Rooms are prepared and masked, coats applied in sequence with drying time between them, and furniture and floors uncovered and put back once the paint has cured.
