How we handle window mastic in Filmore Hill
From a single sill to a whole house of windows, the work is priced before anything is done. Just call 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. We’re often asked to deal with mastic that’s falling out in pieces and draughts coming in around windows and doors, on composite doors, aluminium frames and window sills.
Homes in small places like Filmore Hill often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Filmore Hill and everywhere else we cover.

Windows and doors in Filmore Hill
With historic houses such as Hinton Ampner House (about 4.2 miles west) nearby, there’s older building stock in the area around Filmore Hill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Filmore Hill, the journey is planned in advance: 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.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Filmore Hill questions
Is there a guarantee on window mastic in Filmore Hill?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover Filmore Hill for window mastic?
Yes, Filmore Hill is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Are you fully insured?
Yes. Mr Mastic is fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
When to call us in Filmore Hill
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That is what backing rod is for.
Signs it’s time to call us include:
- Gaps where the sill meets the wall
- Mastic that is falling out in pieces
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
In and around Filmore Hill, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Is VAT in the price?
- How the joint is cleaned and prepared
- How the colour is chosen
- How much experience the applicator has
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Damp problems in the wall away from the window
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
