How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. Somewhere like Shillingford 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.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

About our window mastic in Shillingford
Homes in Shillingford have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for gaps left after new windows were fitted and water coming in at the bottom corners of a door, across aluminium frames, uPVC windows and composite doors.
Homes in small places like Shillingford often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our one-year guarantee.

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Shillingford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

Landlord and commercial work in Shillingford
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Landlords and letting agents in Shillingford can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
What we are called out for in Shillingford
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
Most people get in touch after spotting one of these:
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
Rented homes near Cholsey station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing

What window mastic looks like in Shillingford
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Brightwell Manor (about 1.8 miles south-west) nearby, there’s older building stock in the area around Shillingford 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.
For an older house near a landmark such as Church of St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like St Laurence Church of England (A) School? Then its window and door frames need their mastic kept sound, just like a home’s.

Shillingford: your questions answered
Do you work for landlords with property near Cholsey station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Shillingford for window mastic?
Yes. We work across London and the South East, and Shillingford is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Can you reach windows above the ground floor?
Generally, yes. Access is planned before we start, so mention the height and anything in the way.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- Which sealant suits the joint
- Mould in or behind the old joints
- The old material and how stubborn it is
- The size of the job
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
To help us quote quickly, please include:
- What’s wrong with the joints now
- The rough size of the job
- Any access issues, like height or stairs
- Whether it has been sealed before
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
