DH Painter & Decorator decorates new plaster, extensions and re-skimmed rooms in White Hills, NN2, about 2.8 miles north of Northampton town centre. Dean checks drying, applies a breathable mist coat and finishes walls, ceilings and new joinery once your builder has finished.

Three sources of fresh plaster north of Kingsthorpe

New plaster in and around White Hills tends to come from three quite different places, and each has its own problems:

  • Extensions and remodelling on large plots. The individually built detached houses along Harborough Road North sit on generous plots, one of about 0.4 acre, so there is room to build out.
  • Re-skimmed rooms in the 1930s estate houses. Old walls are often skimmed after stripping layers of paper or after rewiring and new heating.
  • New-build homes at Buckton Fields, the phased development just to the north, where whole houses are handed over with fresh plaster under a builder’s finish.

Large extensions on Harborough Road North

An extension on a big detached house is often a kitchen-family room with a high or vaulted ceiling and a lot of new plaster in one go. That volume of plaster holds a lot of water. We check every wall and ceiling before painting, looking for the even pale colour that shows plaster has dried, and paying attention to corners, window reveals and the junction with the original house, which dry last.

Where the extension joins the old structure there is usually a line of fine cracking as the new work settles. We fill and caulk that after the mist coat has shown it up, rather than before. High ceilings need a tower or podium steps rather than ladders. With mature planting around many of these plots, we also agree where materials and equipment go so borders aren’t trampled. On a shared private drive such as Anchor Drive, neighbours should know if builders’ and decorators’ vans will overlap.

Re-skimming over inter-war walls

A re-skim on a 1930s wall is a smaller job, but it can be trickier. The skim is thin, so it dries faster than a full plaster coat, but it sits over old backing that may carry traces of distemper, paste or oil-based paint. If the plasterer has bonded well, the mist coat goes on as normal. Where it hasn’t, the mist coat often reveals hollow or blistering patches, and those are better cut out and patched now than painted over.

Re-skimmed rooms also leave the original woodwork, picture rails and skirtings sitting next to brand-new walls. The paint lines along those edges show every wobble, so we often repaint the woodwork in the same visit. That is cheaper than coming back later.

Buckton Fields: the builder’s matt and the first proper repaint

Buckton Fields has been built in phases by volume housebuilders. In most new-build homes the walls are finished in a contract matt emulsion: thin, quick to apply and very absorbent, so it marks easily and doesn’t wipe clean. Owners often want to repaint once the house has had its first year to dry out and settle.

That first repaint is not the same as decorating a 1930s room. The plaster is new, so we expect shrinkage cracks at ceiling lines and around door frames, and we treat any patched areas as bare plaster needing a mist coat. Contract matt can be chalky, so we test how well new paint holds before going ahead, and seal where needed before two good finish coats.

The mist coat guide explains drying times and mixing, and our main new plaster and extension page lists everything a typical extension quote covers. For other work in the area, see the White Hills area page.

New plaster & extensions in White Hills: your questions answered

How long should my new extension on Harborough Road North dry before painting?

It depends on plaster thickness, weather and heating, but larger extensions on the detached plots here hold a lot of moisture. A skim coat may be ready in a week or two, while thicker backing plaster takes longer. Dean checks colour and dryness across every wall, especially corners and the join with the original house, before mist coating.

When should I repaint my Buckton Fields new-build?

Many owners wait about a year so the house has dried out and the first settlement cracks have appeared. The builder's contract matt on Buckton Fields homes is thin and absorbent, so repainting sooner can mean more filling later. When we repaint, we fill the cracks, mist coat any patches and test that the new paint bonds before applying finish coats.

My plasterer re-skimmed a room in my 1930s White Hills house. Can it be painted normally?

Usually yes, with a mist coat first. Because inter-war walls may carry old distemper, paste or oil paint under the skim, we watch for blisters or hollow patches when the mist coat goes on. Those are cut out and repaired before finish coats. We often repaint the original skirtings and picture rails at the same visit.

Do you protect gardens when decorating an extension on a large White Hills plot?

Yes. Many Harborough Road North homes have mature wraparound gardens, so we agree where equipment, ladders and materials are stored before we start and keep them off planted borders. Where the house is on a shared private drive like Anchor Drive, it also helps to let neighbours know when vans will be parked.

What customers say about Dean

Most of our work comes from recommendations and returning customers. These are real reviews from customers after the job was finished, in their own words.

More customer reviews

After completing my gates I was then assured Dean was more than competent to repaint the inside of my property from top to bottom. It’s a large 4 bedroom house and was done to a very high standard. Once again I would highly recommend him.

Customer review Gates, then a full four-bedroom interior

I contacted Dean to get the outside of the house painted; the house is all roughcast render. He has done a fantastic job; the house is looking brand new. The same he did for our garage, painted our bedrooms x2, did extra jobs for us like skirtings and door frames, and painted even our gates. I could not recommend him enough; he is attentive, smiling, always on time, and nothing too much; I am so happy with what Dean has done; he went above and beyond. I have recommended him to all my friends and family.
