Builder in Oldham

Oldham is high. Parts of it sit above seven hundred feet, which is unusual for a town this size in England, and the weather knows it. Rain that arrives in Manchester as rain arrives up here driven sideways onto west facing walls, and it does that for most of the winter. The first things to give are always the same: pointing on an exposed gable, a render coat that was never going to hold, and the heads and sills where water is supposed to be thrown clear and has stopped being.

The other thing the hill does is tilt everything. Streets run across slopes rather than along them, so two houses in a terrace can sit a course or more apart, and a back garden can drop a metre in its own length. That shows up in a quote as stepped foundations, a bit of retaining, and drainage that has to be thought about rather than assumed, none of which is a problem and all of which is better known about before the price is fixed than after.

A lot of Oldham is not brick. The older terraces and the cottages out towards the Saddleworth side are local gritstone, and gritstone was laid in lime mortar, not cement. That is not a detail for the sake of it. Lime is softer than the stone and lets a wall dry out through the joints. Cement is harder and tighter, so water that gets in cannot leave the way it came and leaves through the face of the stone instead, which is how a wall that was repointed to tidy it up ends up spalling a few winters later.

So on a stone house the question is never just what the pointing looks like. It is what it is made of, what the wall behind it is doing, and whether taking it out will do more good than leaving it alone. You get that view at the quote, including when the answer is that it does not need doing yet.

The town is really two housing stocks. The older centre and the mill streets are dense terraces: no side access, a back entry if you are lucky, and a yard rather than a garden. Everything for an extension or a refurbishment on one of those goes in and out through the house, which changes how the work is sequenced and how long you live in the middle of it, and it is the single biggest thing people are not warned about.

Then the interwar and post war estates on the lower ground, which are the opposite: semis and short detached runs with a driveway, a side path and a deep roof. Those take a side extension or a rear dormer about as easily as any house in Greater Manchester. Same town, same day, completely different job, which is why a price over the phone for either of them would be a guess.
