Do you need window mastic in Mullenspond?
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
These are the problems we are asked about most:
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Black, perished sealant on frames
Letting a property close to Grateley station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Mullenspond, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. Typical jobs include old mastic that has gone black or come away and water coming in at the bottom corners of a door, across uPVC windows, aluminium frames and window sills.
Around Mullenspond, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Mullenspond, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Old sealant always removed completely
- White, clear, grey or coloured to suit, where the product allows
- We agree the colour with you first
- ARBOMaster approved applicator

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and agents in Mullenspond can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
How it works
Before we leave, we go over the finished joints with you. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. Somewhere like Mullenspond 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.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Mention any tricky access
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

What affects the quote in Mullenspond
You’ll get a clear quote before work begins. It takes into account:
- The number of rooms or windows
- Mould in or behind the old joints
- How easy the joints are to reach
- The old material and how stubborn it is
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

To help us quote quickly, please include:
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height

Common questions in Mullenspond
Can you help a landlord with a rental near Grateley station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Mullenspond within the area you cover?
Yes, Mullenspond is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Looking after it afterwards
To keep the joints looking good and working properly:
- Paint up to the joint, not over it
- Repaint timber before it’s bare
- Check the mastic once a year
- Air rooms to keep condensation down around windows
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Mullenspond homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Amport Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
