Stone Cross: your questions answered
Do you cover Stone Cross for window mastic?

I let a flat near Ham Street station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Where do you work from?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Window mastic in Stone Cross
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, patio & French doors and window sills, and the jobs we see most are draughts coming in around windows and doors and sealant in the wrong colour for the frame.
Homes in small places like Stone Cross often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a 12-month guarantee.

Aftercare tips
Looking after new joints is easy:
- Clear any debris from frame drain holes
- Keep paint off silicone joints
- Don’t aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
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. We match the colour to the frame.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the quote in Stone Cross
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Which sealant suits the joint
Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear quote for the lot.

Do you need window mastic in Stone Cross?
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
These are the problems we are asked about most:
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
- Draughty joints inside around the window
- Black, perished sealant on frames
Letting a property close to Ham Street station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Which colour the sealant will be
- What guarantee comes with the work
- What happens if the job turns out different
- When the joint can take water or movement
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. Somewhere as small as Stone Cross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
