Sand mastic for homes and businesses in Murcott
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on period & listed homes, stone surrounds and tenement windows, and the jobs we see most are window mastic to renew ahead of painting and gaps where the frame meets the masonry.
In a village or hamlet like Murcott, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work comes with a one-year guarantee, wherever you are in Oxfordshire.

Questions from Murcott
Do you work for landlords with property near Islip station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you cover Murcott for sand mastic?
Yes. We work across London and the South East, and Murcott is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Should I use sand mastic or silicone?
We will help you decide. Sand mastic suits many period homes and newer frames suit modern sealant.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Murcott, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator

What affects the quote in Murcott
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- The number and length of the joints
- How many areas need sealing
- The product the joint needs
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- The address or postcode of the job
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

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 per window, depending on the condition of the joints. In a small place like Murcott, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

- New sand mastic is applied and shaped by hand.

Landlords, agents and businesses in Murcott
We also work for property managers and facilities teams in Murcott and across Oxfordshire. Several sites can be quoted together, and we are fully insured for the work.
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
What we’re called out for in Murcott
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Look out for any of the following:
- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
- Cement or filler used on old window joints that has cracked
- A silicone bead on a sash window that spoils the look
Historic houses such as Boarstall Tower, about 2.7 miles east, show how far back building around Murcott goes.
What to look for in a quote
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- How much experience the applicator has
- What happens if they find a problem under the old sealant
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Frames and glazing around Murcott
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Boarstall Tower (about 2.7 miles east) are a reminder that the area around Murcott has older buildings as well as new. 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.
For landlords with property near Islip station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
