Sand mastic for homes and businesses in Botley
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. Typical jobs include old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, across timber door frames, tenement windows and brick reveals.
Around Botley, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
Each job carries a 12-month guarantee, whatever its size.

Do you need sand mastic in Botley?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
Look out for these signs:
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
Letting a property close to Oxford station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

What else we do in Botley
What affects the cost of sand mastic
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- When we can work, for business premises
- Whether there’s mould to deal with
- Access and height
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Asking for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Look over the window mastic once a year
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. In a smaller place like Botley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Questions from Botley
Will you come out to Botley?
Yes, Botley is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do sand mastic in Botley?
Yes, Botley is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
How long will you be here?
A typical job takes anything from a few hours to a full day, depending on how many windows, including the preparation. Your quote will say how long we expect yours to take.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Botley homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Holywell Manor (about 2.3 miles east) are a reminder that the area around Botley has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Botley School, its window and door frames need their mastic kept sound, just like a home’s.
