About our window mastic in Nash

Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on patio & French doors, uPVC windows and timber windows & doors, and common reasons people get in touch are cracked or shrunken mastic around the frame and rushed sealant from a window installation.

Outdoor sealant needs dry, clean surfaces, so work on frames around Nash is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

All our work comes with our 12-month guarantee.

Nash questions

Can you do window mastic in Nash?

Yes, Nash is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.

Is Nash within the area you cover?

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 and businesses?

Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

How do I get a quote for window mastic in Nash?

Size, access and the old material all affect the cost. Call for a quick quote.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Do I have to be there?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Can you reach windows above the ground floor?

Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.

How it works

When we get to you, 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 anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Nash 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. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  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

  • Keep pets and children clear of the area while we work
  • Clear the area around the work
  • Mention any sign-in or site rules at work premises

Different surfaces, different methods

Timber windows & doors

Soft or rotten wood cannot be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.

Window sills

Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. 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.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Windows and doors in Nash

With historic houses such as Goodnestone Park (about 3 miles south) nearby, there’s older building stock in the area around Nash 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For landlords with property near Adisham station, renewing tired window mastic between tenants heads off draught and damp complaints.

Leave it or put it right?

Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Nash, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What we’re called out for in Nash

Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.

Look out for these signs:

  • Cracked or shrunken mastic around the frame
  • Rushed sealant from a window installation
  • Black, perished sealant on frames
  • Damp patches on the reveal after heavy rain

In the older streets around Elmstone Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions to ask before booking

  • What happens if they find a problem under the old sealant
  • How the surfaces are prepared before sealing
  • Are they insured?
  • Which colour the sealant will be
