Questions from Hyde farm estate
Can you do sand mastic in Hyde farm estate?
Yes, Hyde farm estate is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Can parking be tricky for a visit in Hyde farm estate?
Parking in Hyde farm estate, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Do you guarantee sand mastic work?
Our 12-month guarantee covers every job.
What does sand mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Sand mastic in Hyde farm estate
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on period & listed homes, stone surrounds and sash and case windows, and people most often call us about window mastic to renew ahead of painting and gaps between timber frames and stone or brick.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Hyde farm estate is something to talk through when you book.
There’s a 12-month guarantee on every job, whatever its size.

What affects the cost of sand mastic
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- The old material and how stubborn it is
- How many areas need sealing
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- A few photos by email, if you can
- Roughly how big the job is
- Whether it has been sealed before
- The problem you’ve noticed
We don’t publish a price list. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Go gently near the mastic when preparing windows
- Avoid patching sand mastic with silicone
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Signs you need sand mastic in Hyde farm estate
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we are asked about most:
- Silicone on a period window that looks wrong
- Window mastic to renew ahead of painting
- Old sand mastic that has cracked, crumbled or fallen out
- Open joints round the window box
Hyde farm estate is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Advice
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Sashes that rattle, stick or will not open
- Decisions on consent for listed homes
- Broken panes
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

- Brick reveals

Why act early in Hyde farm estate
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Frames and glazing around Hyde farm estate
With historic houses such as Kingswood House (about 2.6 miles east) nearby, there’s older building stock in the area around Hyde farm estate as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
If you live in an older home near St. Stephen's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Balham station, any sash windows need sound mastic to keep draughts and rain out.
