Sand mastic in Tidworth

Sand mastic in Tidworth

Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we will advise if you are redecorating. We work on stone surrounds, tenement windows and timber door frames, and common reasons people get in touch are patchy fillers round a sash window and mastic dropping out of the joint.

Homes around Tidworth range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Do you need sand mastic in Tidworth?

Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.

It’s worth asking for a quote if you see:

  • Gaps round a timber door in stone or brick
  • Wind and rain getting in round a sash window
  • Window mastic to renew ahead of painting
  • Crumbling sand mastic round a window

Schools such as The Wellington Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How to choose a mastic man

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

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, then guaranteed for a year.

How we quote for sand mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • The size of the job

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The problem you’ve noticed
  • The rough size of the job
  • Where the job is, and your postcode
  • Photos by email, if that is easy

Quotes start with a quick conversation. 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.

Why it’s worth doing now in Tidworth

New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In an older home around Tidworth, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Tidworth questions

Will you come out to Tidworth?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is sand mastic in Tidworth guaranteed?

All our work, in Tidworth and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

How long does sand mastic take to go off?

It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme.

Can you replace silicone on a period window with sand mastic?

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

What should I tell you?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. A visit to Tidworth is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We check each window surround and the condition of the joint.
  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. The finish is dressed neatly.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any tricky access
  • Keep children and pets away from the work area

Period and listed homes

Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.

Tidworth homes and the weather

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.

Homes close to Church of the Holy Trinity include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
