About our sand mastic in Hangleton

We work across Hangleton renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you’re dealing with mastic that needs renewing before redecorating and gaps where the frame meets the masonry, we can put it right, whatever the surface.

Around Hangleton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

A one-year guarantee comes as standard.

Hangleton questions

Will you come out to Hangleton?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near Goring-By-Sea station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

Do I need permission for sand mastic on a listed building?

It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How long does the job take?

As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll say how long yours will take.

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.

How much does sand mastic cost in Hangleton?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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.

Different surfaces, different methods

Sash and case windows

A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.

Stone surrounds

Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.

When something else is needed

It helps to know what we can’t do:

  • Sashes that rattle, stick or will not open
  • Crumbling stone or brickwork round the window
  • Putty and glazing repairs

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Surfaces we seal

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

For landlords and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.

What we’re called out for in Hangleton

Paint, silicone or cement used over old mastic causes problems. They do not move with the timber and we normally remove them.

Signs it’s time to call us include:

  • Window mastic to renew ahead of painting
  • Mastic worn away on windows facing the weather
  • Gaps round a timber door in stone or brick
  • Patchy fillers round a sash window

If you look after a building such as Ferring CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What your quote should include

  • Who does the work, and how experienced they are
  • Are they insured?
  • What product goes in the joint
  • Whether all the old sealant comes out first

10 questions to ask before you book

Frames and glazing around Hangleton

Hangleton is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Ecclesden Manor (about 0.9 miles north-west) are a reminder that the area around Hangleton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as St Andrew's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Goring-By-Sea station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens on the day

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. In a small place like Hangleton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. We dress the surface so it sits neatly against the masonry.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Mention if the joints have been sealed before
  • Mention any parking rules near the property

Advice

Why deal with it now?

Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Around Hangleton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

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