Sand mastic in Horspath

Sand mastic in Horspath

Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. Common call-outs are for silicone on a period window that looks wrong and failed mastic on an exposed elevation, across timber door frames, tenement windows and period & listed homes.

Somewhere as small as Horspath, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Your job is guaranteed for a year, as with all our work.

  • Old sand mastic that has cracked, crumbled or fallen out
  • Gaps round a timber door in stone or brick
  • Patchy fillers round a sash window
  • Wind and rain getting in round a sash window

Letting a property close to Oxford station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

How to choose a mastic man

The process

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. Somewhere like Horspath needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on

What the job involves on each surface

Brick reveals

Sand mastic is also used where timber frames meet brick. It suits older brickwork.

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

How we quote for sand mastic

The quote reflects the job in front of us. We take into account:

  • Any mould that needs treating
  • Working hours on commercial sites
  • How much there is to do
  • The product the joint needs

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Common questions in Horspath

I let a flat near Oxford station. Can you help?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Can you do sand mastic in Horspath?

Yes, Horspath is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How do I get a quote for sand mastic in Horspath?

Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access.

Should I check with the council before work on a listed or conservation-area home?

Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Why it’s worth doing now in Horspath

A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Older cottages and farmhouses around Horspath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Horspath homes and the weather

With historic houses such as Garsington Manor (about 1.9 miles south) nearby, there’s older building stock in the area around Horspath as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you look after a building such as Horspath Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Giles, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
