Window mastic for homes and businesses in Holton
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just call 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. Common call-outs are for rain getting in at the frame or under the sill and mastic that has split away from the wall, across patio & French doors, composite doors and aluminium frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Holton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

How we quote for window mastic
We quote each job individually. This is what makes a difference:
- Working hours on commercial sites
- The product the joint needs
- Access and height
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.

Frames and glazing around Holton
With historic houses such as Garsington Manor (about 3.1 miles south) nearby, there’s older building stock in the area around Holton as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you look after a building such as Wheatley Park School, its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door. Somewhere as small as Holton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots aren’t blocked
- Wipe condensation off the frames
- Check the mastic once a year
- Keep solvents and bleach off the sealant
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
When to call us in Holton
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
The problems people normally mention when they call are:
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
In the older streets around The Granary 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
- How long to leave it before use
- Whether all the old sealant comes out first
- What product goes in the joint
- How the surfaces are prepared before sealing
Why act early in Holton
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Holton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
