How we quote for window mastic
For a quick quote, just ask. What matters most is:
- The product the joint needs
- How many rooms, windows or areas are involved
- Access and height
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
When you call or email, these details help:
- Where the property is
- The rough size of the job
- Photos by email, if that’s easy
- Whether it has been sealed before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Window mastic in Appleshaw, done properly
Homes in Appleshaw have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, window sills and patio & French doors, and the jobs we see most are mastic that’s falling out in pieces and cracked internal joints between frame and plaster.
Mastic can only go onto a dry, clean joint, so window work in Appleshaw is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same 12-month guarantee in Appleshaw and across Hampshire.

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Your questions about window mastic in Appleshaw
Is Appleshaw within the area you cover?
Yes. Appleshaw is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Andover station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you have insurance?
Yes, we’re fully insured.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Do not aim a pressure washer at the joints
- Check the mastic once a year
- Wipe condensation off the frames
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Signs you need window mastic in Appleshaw
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
Keep an eye out for any of the following:
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
If you let a flat or house near Andover station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- How long the guarantee is
- Which colour the sealant will be
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. Somewhere as small as Appleshaw, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Frames and glazing around Appleshaw
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.
Homes close to Church of St Peter in the Wood include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Appleshaw St Peter's CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
