What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Bowcombe, access is normally the main thing to plan. 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.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Window mastic in Bowcombe
From a single sill to a whole house of windows, you will get a clear quote before we start. Just call 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. Typical jobs include rain getting in at the frame or under the sill and rushed sealant from a window installation, across aluminium frames, timber windows & doors and uPVC windows.
Homes in small places like Bowcombe 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.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
- A frame that has rotted at the joint

Windows and doors in Bowcombe
The South East is one of the drier parts 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 Carisbrooke Castle (about 1.2 miles north-east) nearby, there’s older building stock in the area around Bowcombe as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St. Nicholas in Castro, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Bowcombe
Is Bowcombe within the area you cover?
Yes, Bowcombe is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is window mastic in Bowcombe guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.

What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The type of sealant required
- How much there is to do
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Helping us quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- How we’d reach the joints
Every job is quoted individually. Simply call 0345 464 0079 or email us and describe the job.
When to call us in Bowcombe
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.
The problems people normally mention when they call are:
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
If you look after a building such as Christ The King College, its window and door frames need their mastic kept sound, just like a home’s.
Before you book anyone
- How the surfaces are prepared before sealing
- Is VAT in the price?
- Is the old sealant removed completely?
- When the joint can take water or movement
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Housing providers, facilities teams and property managers book us too in Bowcombe and across the Isle of Wight. Several sites can go on one quote.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Bowcombe can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
