What happens on the day
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a morning for a couple of windows and a door. For a job in Stoneleigh, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Frames and glazing around Stoneleigh
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Fitznells Manor (about 0.8 miles south) nearby, there’s older building stock in the area around Stoneleigh as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Stoneleigh station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to The Parish Church of St John the Baptist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Damp problems in the wall away from the window
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Common questions in Stoneleigh
I let a flat near Stoneleigh station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Stoneleigh?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does it take to reseal the windows on a house?
The work takes most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Is the new sealant paintable?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Common problems we fix in Stoneleigh
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Any of these means the joints need attention:
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
If you look after a building such as Auriol Junior School, larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
