Window mastic in Dora's Green, done properly
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on window sills, aluminium frames and patio & French doors, and common reasons people get in touch are a bead that doesn’t match the frame and whistling draughts around closed windows.
In a village or hamlet like Dora's Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Window mastic in Dora's Green: local notes
The South East is one of 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 Farnham Castle (about 1.7 miles south-east) are a reminder that the area around Dora's Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Mary's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Farnham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

FAQs for Dora's Green
Will you come out to Dora's Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do window mastic in Dora's Green?
Yes. Our work covers London and the South East, and Dora's Green is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Can new window sealant be painted?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Tell us if you’re decorating and we will choose accordingly.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Where do you work from?
We work from Crawley. Our applicators cover Dora's Green.
How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Looking after it afterwards
To keep the joints looking good and working properly:
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Check the mastic once a year
- Keep jet washers away from the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or email us.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Do you need window mastic in Dora's Green?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
For site and facilities teams at buildings such as Crondall Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Dora's Green
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. Where a wall is exposed, as many are in small places like Dora's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- A 12-month guarantee on all work

What affects the quote in Dora's Green
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Mould in or behind the old joints
- When we can work, for business premises
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the job is, and your postcode
- Pictures of the joints, sent by email
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How the visit 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 anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Somewhere as small as Dora's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
