Looking after it afterwards

Aftercare is simple, and it makes a real difference:

  • Check the mastic when you check the paintwork
  • Ask us before painting near the mastic
  • Sort the mastic before the decorators arrive
  • Keep modern sealant off the mastic

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

About our sand mastic in Ruislip Manor

Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you have wind and rain getting in round a sash window and tired mastic found when preparing windows for paint, we can put it right, on brick reveals, timber door frames and period & listed homes alike.

London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Ruislip Manor is something to talk through when you book.

Whatever the size of the job, it’s backed by our one-year guarantee.

Questions from Ruislip Manor

Can you help a landlord with a rental near West Ruislip station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.

Do you cover Ruislip Manor for sand mastic?

Yes. We work across London and the South East, and Ruislip Manor is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

When will the new mastic be hard?

It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.

Can I add another job to the visit?

Yes. Just list everything you need and you will get one quote.

Can old silicone round a sash window be swapped for sand mastic?

Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

How the visit works

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for a single window, longer for several, depending on how much there is to do. In Ruislip Manor, 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. We check the window surrounds and agree which joints need renewing.
  2. We rake out the old mastic and clean the joint.
  3. Deep voids are packed so the mastic is the right thickness.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Advice

When something else is needed

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Damaged stone surrounds
  • Timber that has rotted
  • Sashes that rattle, stick or won’t open

If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What we seal

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

What happens if it’s left?

If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Ruislip Manor, the repair is bigger than a sealant job.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What you get with us

  • 180+ five-star Google reviews
  • Anti-fungal sanitary silicone in wet areas
  • Full insurance on every job
  • Any old sealant cut out fully, not covered over

Windows and doors in Ruislip Manor

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.

Schools such as Lady Bankes Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to West Ruislip station? Then any sash windows need sound mastic to keep draughts and rain out. Ruislip Manor is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
