FAQs for Shortgate
Can you do window mastic in Shortgate?
Yes, Shortgate is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is Shortgate within the area you cover?
Yes, smaller places are covered as well as towns. 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 reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Window mastic in Shortgate
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have water coming in at the bottom corners of a door and cracked or shrunken mastic around the frame, we can help, on aluminium frames, uPVC windows and patio & French doors alike.
Homes in small places like Shortgate often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Shortgate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Whether there’s mould to deal with
- The size of the job
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work

Different surfaces, different methods
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
Frames and glazing around Shortgate
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Glyndebourne (about 3.5 miles south-west) nearby, there’s older building stock in the area around Shortgate as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Advice
What we’re called out for in Shortgate
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- Draughty joints inside around the window
If you let a flat or house near Uckfield station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include
- What the quote includes, VAT included or not
- Are they insured?
- Is the old sealant removed completely?
- When the joint can take water or movement
