If you have old mastic that has gone black or come away and draughts coming in around windows and doors, we can put it right, on patio & French doors, uPVC windows and timber windows & doors alike.

Around Cryers Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

Landlords, agents and businesses in Cryers Hill

Letting agents and landlords in Cryers Hill can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

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.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

What we’re called out for in Cryers Hill

Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.

Any of these means the joints need attention:

  • Draughts coming in around windows and doors
  • Old mastic that has gone black or come away
  • Cracked internal joints between frame and plaster
  • Leaking joints at the ends of sills

If you look after a building such as Great Kingshill Church of England Combined School, the mastic around its windows and doors needs looking after like any other building’s.

10 questions to ask before you book

Your questions about window mastic in Cryers Hill

Do you work for landlords with property near High Wycombe station?

Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Do you cover smaller places like Cryers Hill?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can I add another job to the visit?

Yes, we can. Several rooms, windows or areas can go on one quote.

When is the sealant fully cured?

Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.

How much does window mastic cost in Cryers Hill?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Can you get sealant to suit coloured frames?

Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.

Why deal with it now?

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Where a wall is exposed, as many are in small places like Cryers Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What window mastic looks like in Cryers Hill

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hughenden Manor (about 1.3 miles south-west) are a reminder that the area around Cryers Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For landlords with property near High Wycombe station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of the Good Shepherd, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition

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

  • Keep paint off silicone joints
  • Keep drainage slots and sill grooves clear
  • Wipe condensation off the frames
  • Avoid harsh chemicals near the mastic

Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.

Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

How it works

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes most of a day for a typical house, less for a few frames. Somewhere as small as Cryers Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  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.

How to prepare

  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before
