Quotes for window mastic in Lower Eashing

Jobs vary more than people expect. The main factors:

  • The type of sealant required
  • Whether there’s mould to deal with
  • Access and height
  • When we can work, for business premises

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we need to know

When you contact us, these details help:

  • Photos by email, if that is easy

  • Any previous sealing or DIY work
  • If it’s domestic, commercial or a hotel

We don’t publish a price list. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Lower Eashing

Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In a small place like Lower Eashing, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Combining jobs into one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.

Why book with us

  • Any old sealant cut out fully, not covered over
  • We leave the area clean and tidy
  • Trusted Arbo and Everbuild sealants
  • Sanitary silicone with an anti-fungal additive in wet areas

Lower Eashing questions

Do you work for landlords with property near Godalming station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Is Lower Eashing within the area you cover?

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.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

How long will my window job take?

The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.

What does window mastic cost?

It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you seal inside as well as outside?

Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.

Do you have insurance?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

For landlords and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured for the work.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Ventilate rooms so frames don’t stay wet inside
  • Keep paint and stain on wooden frames in good order
  • Don’t aim a pressure washer at the joints
  • Do not paint over the silicone

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What window mastic looks like in Lower Eashing

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 Loseley Park (about 2.7 miles north-east) nearby, there’s older building stock in the area around Lower Eashing as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For site and facilities teams at buildings such as St Mary's CofE Voluntary Controlled Infant School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Do you need window mastic in Lower Eashing?

Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

The most common problems we see are:

  • Cold air getting in at the frame edge
  • Gaps between the frame and the inside reveal
  • Water coming in at the bottom corners of a door
  • Gaps where the sill meets the wall

Rented homes near Godalming station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Our hiring checklist

When it isn’t the sealant

In fairness, there are a few things sealant won’t fix:

  • Rotten timber, which needs a joiner first
  • A door that needs adjusting, rehanging or new seals
  • Condensation trapped between the panes

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

What we seal

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

The process

Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes most of a day for a typical house, less for a few frames. In a small place like Lower Eashing, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

How to prepare

  • Clear items away from the joints we are working on
  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
