Sand mastic in Brock Hill, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on stone surrounds, period & listed homes and sash and case windows, and common reasons people get in touch are silicone on a period window that looks wrong and tired mastic found when preparing windows for paint.
In a village or hamlet like Brock Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee.

Common questions in Brock Hill
Will you come out to Brock Hill?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Wickford station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will say how long yours will take.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.

What sealant work can’t fix
It helps to know what we cannot do:
- Planning or listed building consent (your local planning authority decides)

- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

Brock Hill homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Wickford station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Margaret, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landlords, agents and businesses in Brock Hill
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a small place like Brock Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
Why us?
- More than 20 years in sealant work
- We are fully insured
- Any old sealant cut out fully, not covered over
- Anti-fungal silicone where joints get wet
How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Brock Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Before we arrive
- Tell us about any water getting in
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.

When to call us in Brock Hill
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
The problems people generally mention when they call are:
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
For site and facilities teams at buildings such as Beauchamps High School, the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How much experience the applicator has
- Whether they seal over old material or remove it
- How hidden problems are handled
- What product goes in the joint
Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
