About our window mastic in Badshot Lea

Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have sealant in the wrong colour for the frame and damp patches on the reveal after heavy rain, we can put it right, on composite doors, patio & French doors and window sills alike.

Mastic can only go onto a dry, clean joint, so window work in Badshot Lea is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

Whatever the size of the job, you get the same one-year guarantee in Badshot Lea and across Surrey.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we cannot put right

A few problems are outside what sealant work can do:

  • Rotten timber, which needs a joiner first
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window

If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.

Signs you need window mastic in Badshot Lea

Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.

These are the problems we are asked about most:

  • Whistling draughts around closed windows
  • A bead that doesn’t match the frame
  • Rushed sealant from a window installation
  • Cracked or shrunken mastic around the frame

For site and facilities teams at buildings such as Badshot Lea Village Infant School, the mastic around its windows and doors needs looking after like any other building’s.

Questions to ask before booking

  • What happens if the job turns out different
  • Whether VAT is included
  • What guarantee comes with the work
  • Which colour the sealant will be

How to choose a mastic man

How the visit works

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere like Badshot Lea needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Plan for the work area to be out of bounds to pets and children

Windows and doors in Badshot Lea

Historic houses like Farnham Castle (about 1.8 miles south-west) are a reminder that the area around Badshot Lea 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Aldershot station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around St George's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a small place like Badshot Lea, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What you get with us

  • Anti-fungal silicone where joints get wet
  • Any old sealant cut out fully, not covered over
  • Sealant colour chosen to suit
  • We agree the colour with you first

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Wipe condensation off the frames
  • Repaint timber before it’s bare
  • Clean frames with a soft cloth and soapy water
  • Keep paint off silicone joints

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.

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.
