Sand mastic near Peacehaven

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Sand mastic in Peacehaven

Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on period & listed homes, stone surrounds and sash and case windows, and the jobs we see most are patchy fillers round a sash window and window mastic to renew ahead of painting.

Houses in smaller places like Peacehaven can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What sealant work can’t fix

New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:

  • Sashes that rattle, stick or won’t open
  • Putty and glazing repairs
  • Rotten sashes, sills or window boxes (a joiner’s job)

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Surfaces we seal

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

What we are called out for in Peacehaven

Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.

The most common problems we see are:

  • Gaps between timber frames and stone or brick
  • Cement or filler used on old window joints that has cracked
  • Cracked mastic round a front door frame
  • Draughts and rain around sash boxes

For landlords with property near Newhaven Town station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What your quote should include

Quotes for sand mastic in Peacehaven

You’ll get a clear quote before any work starts. It’s based on:

  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • Mould in or behind the old joints
  • How many areas need sealing

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What we need to know

There’s no need for technical detail. Just tell us:

  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • The type of property
  • Where the job is, and your postcode

Every job is quoted individually. Just ring 0345 464 0079 or drop us an email with the details and send photos if you have them.

Landlords, agents and businesses in Peacehaven

Landlords and agents in Peacehaven can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Why deal with it now?

Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In an older home around Peacehaven, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What you get with us

  • Arbo and Everbuild products
  • Full insurance on every job
  • A 12-month guarantee on all work
  • We never seal over old sealant

FAQs for Peacehaven

Does living near the coast affect sand mastic in Peacehaven?

Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.

Do you work for landlords with property near Newhaven Town station?

Yes, rental work is part of what we do. 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 work begins.

What is sand mastic?

Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

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

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

How the visit works

You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Parking around Peacehaven is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about parking restrictions
  • Let us know about stairs, lifts or work at height

Advice

What sand mastic looks like in Peacehaven

Peacehaven is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near Ascension Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Peacehaven Community School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
