Window mastic in Stanswood, done properly
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, composite doors and aluminium frames, and the jobs we see most are whistling draughts around closed windows and cracked or shrunken mastic around the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stanswood is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard.

To be straight with you, there are a few things sealant will not fix:

- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes

How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The type of sealant required
- The amount of work
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What we need to know
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is

Frames and glazing around Stanswood
Stanswood is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Osborne House (about 4.8 miles south-east) nearby, there’s older building stock in the area around Stanswood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Hamble station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Stanswood: your questions answered
Will you come out to Stanswood?
Yes. Stanswood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Hamble station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Do you have insurance?
Yes. We are fully insured for every job we do.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
When to call us in Stanswood
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
People normally contact us when they notice something like this:
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
Homes close to St George include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Different surfaces, different methods
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Stanswood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- 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.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
