Window mastic for homes and businesses in Shirrell Heath
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Typical jobs include cracked or shrunken mastic around the frame and cracked sealant at the sill ends, across window sills, composite doors and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Shirrell Heath is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What affects the quote in Shirrell Heath
You’ll get a clear quote before we start. It takes into account:
- Whether there’s mould to deal with
- The number of rooms or windows
- Whether the work is at height
- The number and length of the joints
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any access issues, like height or stairs
- Where the job is, and your postcode
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why act early in Shirrell Heath
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Shirrell Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Common questions in Shirrell Heath
Is Shirrell Heath within the area you cover?
Yes. Shirrell Heath is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Botley station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is the new sealant paintable?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Do you guarantee window mastic?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
What the job involves on each surface
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Landlords, agents and businesses in Shirrell Heath
Landlords and letting agents in Shirrell Heath can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
How it works
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Shirrell Heath, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

Shirrell Heath homes and the weather
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.
Schools such as St John the Baptist Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Botley station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St John, the joint between an old wall and a newer frame is generally the first place rain gets in.

How to look after the new joints
To keep the joints looking good and working properly:
- Ventilate rooms so frames do not stay wet inside
- Wash the frames with mild soapy water
- Make sure the drainage slots aren’t blocked
- Do not paint over the silicone
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
