About our window mastic in Barcombe
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. Common call-outs are for a bead that doesn’t match the frame and leaking joints at the ends of sills, on patio & French doors, aluminium frames and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Barcombe is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Why act early in Barcombe
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Barcombe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Landlords, agents and businesses in Barcombe
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
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.
How we quote for window mastic
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- Any working-time requirements on site
- The amount of work
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
What window mastic looks like in Barcombe
With historic houses such as Glyndebourne (about 3.2 miles south-east) nearby, there’s older building stock in the area around Barcombe 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’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near The Parish Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Barcombe Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

When it is not the sealant

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Somewhere as small as Barcombe, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Advice
What we’re called out for in Barcombe
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Keep an eye out for these signs:
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
Letting a property close to Cooksbridge station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Barcombe questions
Will you come out to Barcombe?
Yes. Barcombe is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What does window mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
