Sand mastic for Stadhampton homes and businesses

Sand mastic for homes and businesses in Stadhampton

If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on timber door frames, sash and case windows and period & listed homes, and people most often call us about crumbling sand mastic round a window and weathered mastic on the most exposed windows.

Homes in small places like Stadhampton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

What happens if it’s left?

If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a small place like Stadhampton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

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

Do you need sand mastic in Stadhampton?

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

The most common problems we see are:

  • Failed mastic on an exposed elevation
  • Tired mastic found when preparing windows for paint
  • Silicone on a period window that looks wrong
  • Wind and rain getting in round a sash window

In the older streets around Church of St John the Baptist, the joint between an old wall and a newer frame is usually the first place rain gets in.

Before booking anyone

  • Whether they seal over old material or remove it
  • How the joint is cleaned and prepared
  • Whether they’re fully insured
  • Which sealant they’ll use, and why

The process

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Stadhampton, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Preparing for the visit

  • Clear items away from the joints we’re working on
  • Mention if the joints have been sealed before
  • Mention any parking rules near the property

What affects the cost of sand mastic

There’s no set price list. The quote depends on:

  • The amount of work
  • When we can work, for business premises
  • Any mould that needs treating
  • The product the joint needs

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • Whether it’s a home or a business
  • The address or postcode of the job
  • Photos by email, if that’s easy

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. When it suits you, phone 0345 464 0079 or email us.

What sand mastic looks like in Stadhampton

Historic houses like Garsington Manor (about 2.5 miles north-west) are a reminder that the area around Stadhampton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

If you look after a building such as Stadhampton Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Radley station, any sash windows need sound mastic to keep draughts and rain out.

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

Check with your local planning authority. They decide whether consent is needed for work to your windows.

Is sand mastic better than silicone for my windows?

That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames generally get a flexible sealant.

Do you work for hotels and businesses?

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

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

Can sand mastic be painted?

Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Different surfaces, different methods
