What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- When we can work, for business premises
- The number and length of the joints
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.
What we need to know
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- A few photos by email, if you can
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or send us an email.
Window mastic in Broughton
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We work on uPVC windows, aluminium frames and timber windows & doors, and people most often call us about sealant in the wrong colour for the frame and gaps where the sill meets the wall.
Outdoor sealant needs dry, clean surfaces, so work on frames around Broughton is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
FAQs for Broughton
Do you work for landlords with property near Banbury station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Broughton?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
What should I tell you?
Let us know what needs doing and where. If we need more, we will ask.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Do not use solvent cleaners on the joint
- Paint up to the joint, not over it
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
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.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What happens if it’s left?
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. Older cottages and farmhouses around Broughton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What else we do in Broughton
Frames and glazing around Broughton
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Broughton Castle (about 0.3 miles south-west) nearby, there’s older building stock in the area around Broughton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Bishop Carpenter Church of England Aided Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Banbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a morning for a couple of windows and a door. Somewhere as small as Broughton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
Before we arrive
- Tell us about any water getting in
- Let us know about parking restrictions
- Mention any tricky access
