How we handle sand mastic in Norwood Hill
Across Norwood Hill, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Typical jobs include old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, on stone surrounds, tenement windows and period & listed homes.
Homes in small places like Norwood Hill 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Clear gutters so water does not pour onto the windows
- Do not paint over the new mastic
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Why act early in Norwood Hill
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Norwood Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

FAQs for Norwood Hill
Will you come out to Norwood Hill?
Yes. Norwood Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers 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 Horley station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do you guarantee sand mastic work?
You get our one-year guarantee on every job.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work generally takes a few hours for a single window, longer for several. Somewhere as small as Norwood Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in

Advice
Quotes for sand mastic in Norwood Hill
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- The size of the job
- How many rooms, windows or areas are involved
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- Whether it’s a home or a business
- If someone has resealed it before
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job and send pictures if you have them.
When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Cracked or broken glass
- Sashes that rattle, stick or won’t open
- Crumbling stone or brickwork round the window
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
