Window Mastic in Purbrook
Our applicators work in Purbrook on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Black, perished sealant on frames
How it works
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are. In Purbrook, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Common problems we fix in Purbrook
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.
Common reasons people contact us include:
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
- Draughty joints inside around the window
- Black, perished sealant on frames
If you live in an older home near Church of St John, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before booking
- What guarantee comes with the work
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

For landlords and businesses
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
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. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Common questions in Purbrook
Does the coastal weather in Purbrook affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Bedhampton station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you do upstairs windows?
Normally, yes. We plan safe access before the job.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you work in Purbrook?
Yes. We work in Purbrook and the rest of Hampshire. For a quote, phone 0345 464 0079 or send us an email.
What affects the quote in Purbrook
We do not publish a price list. What we look at:
- The type of sealant required
- The amount of work
- Mould in or behind the old joints
- Whether the work is at height
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- The rough size of the job
- If someone has resealed it before
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.
Purbrook homes and the weather
Purbrook is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Purbrook Junior School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Bedhampton station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
