Need sand mastic in Luxted?

Why deal with it now?

Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Why book with us

  • Old sealant always removed completely
  • Quality sealants from Arbo and Everbuild
  • Tidy, careful work
  • Sanitary silicone with an anti-fungal additive in wet areas

Sand mastic in Luxted

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out, we can help, on tenement windows, stone surrounds and timber door frames alike.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.

Every job is covered by our 12-month guarantee.

What we are called out for in Luxted

Rain on the window surround works into any crack and pushes it out. Exposed elevations usually fail first.

These are the problems we are asked about most:

  • Draughts and rain around sash boxes
  • Old sand mastic that has cracked, crumbled or fallen out
  • Gaps round a timber door in stone or brick
  • Mastic worn away on windows facing the weather

Rented homes near Chelsfield station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Questions to ask before you book

  • What product goes in the joint
  • How the surfaces are prepared before sealing
  • Whether they seal over old material or remove it
  • Are they insured?

Luxted: your questions answered

Is parking a problem for a job in Luxted?

Parking in Luxted, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Can you help a landlord with a rental near Chelsfield station?

Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.

Can sand mastic be painted?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few photos.

Do you guarantee sand mastic work?

Our 12-month guarantee covers every job.

Can you work on commercial sites?

Yes. Larger jobs can be planned room by room or area by area to suit the site.

Do I need to be at home?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

Different surfaces, different methods

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.

Stone surrounds

Sand mastic sits naturally against stone. It finishes to look like part of the surround.

When it isn’t the sealant

We’ll always be straight with you, so here’s what new sealant will not do:

  • Planning or listed building consent (your local planning authority decides)
  • Sashes that need overhauling
  • Timber that has rotted

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

Surfaces we seal

  • Sash and case windows
  • Brick reveals
  • Tenement windows
  • Period & listed homes
  • Stone surrounds
  • Timber door frames

Luxted homes and the weather

With historic houses such as Down House (about 0.5 miles north) nearby, there’s older building stock in the area around Luxted as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

Luxted is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you live in an older home near Church of St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

For landlords and businesses

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

What we do, step by step

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In Luxted, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Mention any parking rules near the property
  • Plan for the work area to be out of bounds to pets and children
