Window mastic near Shamley Green

What we do, step by step

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Shamley Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking each window and door with you.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

Surface by surface

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.

Window sills

Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Common problems we fix in Shamley Green

Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

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

  • Gaps where the sill meets the wall
  • Water coming in at the bottom corners of a door
  • Draughts coming in around windows and doors
  • Draughty joints inside around the window

Schools such as Wonersh and Shamley Green CofE Aided Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What your quote should include

  • How long the guarantee is
  • Whether all the old sealant comes out first
  • When the joint can take water or movement
  • How much experience the applicator has

Choosing a sealant specialist

Common questions in Shamley Green

Will you come out to Shamley Green?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for landlords with property near Chilworth station?

Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Can I paint over the new sealant?

Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.

How long does it take to reseal the windows on a house?

The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do you have sealant for grey or black windows?

Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.

What does window mastic cost?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Why act early in Shamley Green

A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Shamley Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Why book with us

  • Trusted Arbo and Everbuild sealants
  • Homes, businesses and hotels
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Colour picked to suit the job

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Soft or decayed wood in the frame
  • Faulty window hardware
  • Damp coming through the wall itself rather than the frame joint

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

  • Window sills
  • Patio & French doors
  • Composite doors
  • Timber windows & doors
  • Aluminium frames

Window mastic in Shamley Green: local notes

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. With historic houses such as Chilworth Manor (about 2.5 miles north) nearby, there’s older building stock in the area around Shamley Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Rented homes near Chilworth station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Shamley Green is about 5 miles south-east of Guildford, in Surrey.

Should I try it myself first?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

For landlords and businesses

We also work for property managers and facilities teams in Shamley Green and across Surrey. We can quote a run of properties together, and we’re fully insured.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
