- Black, perished sealant on frames
How we handle window mastic in North Baddesley
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with black, perished sealant on frames and draughts coming in around windows and doors, we can put it right, whatever the surface.
Many houses in smaller places like North Baddesley have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Big or small, it’s backed by our one-year guarantee in North Baddesley and across Hampshire.

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- Which sealant suits the joint
- Any mould that needs treating
- Any working-time requirements on site
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.
Asking for a quote
When you call or email, it’s useful to know:
- The problem you’ve noticed
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
What we cannot put right
We will not take on work that will not last, so here’s what sealant cannot put right:
- Damp problems in the wall away from the window
- Worn gaskets, brush seals or a door that has dropped
- Condensation trapped between the panes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Composite doors
- uPVC windows
- Patio & French doors
- Aluminium frames
- Timber windows & doors
- Window sills
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Window mastic in North Baddesley: local notes
With historic houses such as South Stoneham House (about 4.1 miles south-east) nearby, there’s older building stock in the area around North Baddesley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Letting a property close to Romsey station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as North Baddesley Junior School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Local landmarks in North Baddesley
We work in homes and buildings around The Mountbatten School, among other places. For rail, the closest station is Romsey station, roughly 2.3 miles north-west of the centre.

What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around North Baddesley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

How the visit works
The work is kept neat and contained to the area we’re working on. Expect the work to take most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. A visit to North Baddesley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

What else we do in North Baddesley
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
