Window mastic for homes and businesses in Abbotswood
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have draughty joints inside around the window and sealant in the wrong colour for the frame, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Abbotswood is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same one-year guarantee in Abbotswood and across Hampshire.

Your questions about window mastic in Abbotswood
Is Abbotswood within the area you cover?
Yes, Abbotswood is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Abbotswood in your area for window mastic?
Yes, Abbotswood is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Does the work come with a guarantee?
Yes. Every job comes with our one-year guarantee, and we are ARBOMaster approved applicators.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Where are you based?
We work from Crawley. We cover Abbotswood and the rest of Hampshire, along with the rest of our area.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Honest limits
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- A sash or casement that won’t close properly
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

What affects the quote in Abbotswood
We do not publish a price list, because jobs vary so much. What we look at:
- The size of the job
- How many rooms, windows or areas are involved
- The type of sealant required
- Whether the work is at height
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- Any access issues, like height or stairs
If you’re in Abbotswood and need window mastic, call 0345 464 0079 or email us. Tell us what the problem is and where, and we will agree the price before any work begins.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Abbotswood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Do you need window mastic in Abbotswood?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
People normally contact us after spotting something like this:
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
- A bead that doesn’t match the frame
- Water coming in at the bottom corners of a door
Homes close to St Swithun's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Are they insured?
- Who turns up on the day
How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. In a small place like Abbotswood, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Advice
Windows and doors in Abbotswood
With historic houses such as Mottisfont Abbey (about 3.2 miles north-west) nearby, there’s older building stock in the area around Abbotswood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Cupernham Infant School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Romsey station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
