Window mastic near Vernham Street

What sealant work can’t fix

Before you book, it’s worth knowing the limits too:

  • Damp coming through the wall itself rather than the frame joint
  • A door that needs adjusting, rehanging or new seals
  • Faulty window hardware

If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Joints and surfaces we work on

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

How we handle window mastic in Vernham Street

Around Vernham Street we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have water coming in at the bottom corners of a door and whistling draughts around closed windows, we can put it right, whatever the surface.

Somewhere as small as Vernham Street, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

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

What affects the cost of window mastic

Some jobs are bigger than they look, and some smaller. The main factors:

  • Access and height
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating
  • The number of rooms or windows

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

Helping us quote

To make quoting easier, please include:

  • Access, such as stairs, a lift or height
  • Where the property is
  • Roughly how big the job is
  • What the problem is, such as mould, gaps, leaks or cracking

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

For landlords and businesses

Landlords and letting agents in Vernham Street can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Windows and doors in Vernham Street

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stargroves (about 4.2 miles north-east) are a reminder that the area around Vernham Street 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.

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

How the visit works

The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere like Vernham Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

How to prepare

  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
  • Tell us about any water getting in

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Wipe condensation off the frames
  • Keep jet washers away from the mastic
  • Walk round the house once a year and look at the joints
  • Keep timber frames painted

Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.

A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

When to call us in Vernham Street

Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.

Signs it’s time to call us include:

  • Draughts coming in around windows and doors
  • Leaking joints at the ends of sills
  • Mastic that has split away from the wall
  • Mastic that’s falling out in pieces

If you look after a building such as Vernham Dean Gillum's Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions to ask before you book

  • Are they insured?
  • What the cure time is
  • How long the guarantee is
  • How much experience the applicator has
