About our sand mastic in North Gorley
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you have mastic that needs renewing before redecorating and cement or filler used on old window joints that has cracked, we can help.
Homes in small places like North Gorley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we are called out for in North Gorley
Water gets into small cracks in the mastic and pushes it out. Exposed elevations generally fail first.
Look out for these signs:
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
Homes close to Church of the Holy Ascension include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Questions from North Gorley
Is sand mastic in North Gorley guaranteed?
All our work, in North Gorley and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to North Gorley?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They’ll tell you if consent is needed.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will talk you through it.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you fully insured?
Yes. We are fully insured.
What affects the quote in North Gorley
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Whether there’s mould to deal with
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- The address or postcode of the job
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents and landlords in North Gorley can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
Aftercare tips
A little care helps the new joints last. We recommend:
- Plan mastic work ahead of painting
- Look over the window mastic once a year
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Why it’s worth doing now in North Gorley
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like North Gorley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What sand mastic looks like in North Gorley
With historic houses such as Breamore House (about 4.5 miles north) nearby, there’s older building stock in the area around North Gorley 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 is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Hyde Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
