About our window mastic in Monk Sherborne
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have black, perished sealant on frames and cracked internal joints between frame and plaster, we can help, whatever the surface.
In a village or hamlet like Monk Sherborne, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. Somewhere as small as Monk Sherborne, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What we cannot put right
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Aluminium frames
- Composite doors
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Window sills
What affects the cost of window mastic
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- The number of rooms or windows
- Which sealant suits the joint
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
To help us quote quickly, let us know:
- Roughly how big the job is
- Any previous sealing or DIY work
- The type of property
- Any access issues, like height or stairs
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
What we are called out for in Monk Sherborne
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.
Look out for any of the following:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- Black, perished sealant on frames
- Leaking joints at the ends of sills
In the older streets around Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Whether the sealant suits the joint
- Are they insured?
- How the colour is chosen
- Whether they seal over old material or remove it
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Windows and doors in Monk Sherborne
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. With historic houses such as The Vyne (about 1.7 miles east) nearby, there’s older building stock in the area around Monk Sherborne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as The Priory Primary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Basingstoke station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens if it’s left?

How long will my window job take?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.

Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
