Window mastic for homes and businesses in Gallows Green
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with damp patches on the reveal after heavy rain and black, perished sealant on frames, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Gallows Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes most of a day for a typical house, less for a few frames, depending on the size of the job. For a village or hamlet like Gallows Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- 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.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Advice
Why it’s worth doing now in Gallows Green
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Gallows Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Landlord and commercial work in Gallows Green
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 that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Do not aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Gallows Green questions
Do you cover smaller places like Gallows 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.
I let a flat near Marks Tey station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How we quote for window mastic
We quote each job individually. These are the things that affect it:
- Access and height
- When we can work, for business premises
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- Any previous sealing or DIY work
- The address or postcode of the job
- A few photos by email, if you can
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.

Window mastic in Gallows Green: local notes
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.
Managing a site like Holy Trinity CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Margaret and St Catherine, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Marks Tey station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
