Window & door mastic in Faberstown, Hampshire
Professional window mastic in and around Faberstown, with every bit of old sealant taken out first and a 12-month guarantee.
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
Window mastic for homes and businesses in Faberstown
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on uPVC windows, window sills and patio & French doors, and common reasons people get in touch are cold air getting in at the frame edge and untidy mastic left by window fitters.
Outdoor sealant needs dry, clean surfaces, so work on frames around Faberstown is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- When we can work, for business premises
- The product the joint needs
- How easy the joints are to reach
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 will go through it with you.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- If someone has resealed it before

Honest limits
We will not take on work that will not last, so here’s what sealant cannot put right:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Window sills
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Aluminium frames
- Composite doors
Signs you need window mastic in Faberstown
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Sealant in the wrong colour for the frame
- Mastic that’s falling out in pieces
- Gaps left after new windows were fitted
- Water coming in at the bottom corners of a door
If you live in an older home near Church of St Peter in the Wood, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- Which colour the sealant will be
- What product goes in the joint
- What the cure time is
- Is VAT in the price?
Frames and glazing around Faberstown
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.
Rented homes near Andover station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. Somewhere as small as Faberstown, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Surface by surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
