Your questions about window mastic in Bullbrook
Do you work for landlords with property near Martins Heron station?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Bullbrook?
Yes. Bullbrook is within the area we cover, which takes in towns, villages and rural addresses. 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 several jobs on one visit?
Yes. More than one area can go on one quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Does the work come with a guarantee?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Do you seal inside as well as outside?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Window mastic in Bullbrook
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have draughts coming in around windows and doors and mastic that has split away from the wall, we can put it right, whatever the surface.
In a smaller place like Bullbrook, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What else we do in Bullbrook
Frames and glazing around Bullbrook
Historic houses like St Leonard's Hill (about 4.9 miles north-east) are a reminder that the area around Bullbrook has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Martins Heron station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door. In a smaller place like Bullbrook, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- 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.
How to prepare
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

Advice
Landlord and commercial work in Bullbrook
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents and landlords in Bullbrook can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In a smaller place like Bullbrook, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
When to call us in Bullbrook
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
Managing a site like Holly Spring Junior School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Which sealant they’ll use, and why
- Which colour the sealant will be
- How the joint is cleaned and prepared
- How long the guarantee is
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
