Window & door mastic in Wickham, Hampshire
Window and door frames in Wickham need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
Common problems we fix in Wickham
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.
Most people get in touch when they notice something like this:
- Mastic that has split away from the wall
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Black, perished sealant on frames
In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Window mastic in Wickham, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you’re dealing with rain getting in at the frame or under the sill and hard, cracked sealant around windows, we can put it right, on timber windows & doors, composite doors and aluminium frames alike.
Around Wickham, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same 12-month guarantee.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

FAQs for Wickham
Is Wickham in your area for window mastic?
Yes, Wickham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Fareham station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

What affects the quote in Wickham
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Any working-time requirements on site
- Which sealant suits the joint
- The number of rooms or windows
Doing several joints on one visit generally makes better use of the time than several visits. We’ll send you a clear quote for the lot.

The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a job in Wickham, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
