What we do, step by step

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several. In Bedfont, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

How we handle sand mastic in Bedfont

Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We work on stone surrounds, sash and case windows and period & listed homes, and common reasons people get in touch are cracked mastic round a front door frame and modern sealant on a period surround.

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.

You get a one-year guarantee, the same in Bedfont as everywhere else we work.

Can I do it myself?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What the job involves on each surface

Sash and case windows

On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.

Timber door frames

Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.

Quotes for sand mastic in Bedfont

The price is agreed before any work begins. It takes into account:

  • The old material and how stubborn it is
  • Any mould that needs treating
  • Which sealant suits the joint
  • The number and length of the joints

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Asking for a quote

When you contact us, these details help:

  • Where the property is
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Roughly how big the job is

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or drop us an email.

Common questions in Bedfont

I let a flat near Heathrow Terminal 4 Rail station. Can you help?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Can parking be tricky for a visit in Bedfont?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

How long will you be here?

That depends on the amount of work, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.

Can sand mastic be painted?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.

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

Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Honest limits

A few problems are outside what sealant work can do:

  • Putty and glazing repairs
  • Timber that has rotted
  • Decisions on consent for listed homes

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

Why act early in Bedfont

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a flat in Bedfont, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Bedfont homes and the weather

In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For landlords with property near Heathrow Terminal 4 Rail station, older sash windows in a rental need their mastic kept sound to keep the weather out. Bedfont is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
