FAQs for Whitley Wood
I let a flat near Reading Green Park station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Whitley Wood?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
About our sand mastic in Whitley Wood
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you have silicone on a period window that looks wrong and gaps where the frame meets the masonry, we can help.
Homes around Whitley Wood range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Signs you need sand mastic in Whitley Wood
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
Letting a property close to Reading Green Park station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Plan mastic work ahead of painting
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Frames and glazing around Whitley Wood
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. Historic houses like Stratfield Saye House (about 4.9 miles south) are a reminder that the area around Whitley Wood 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.
In the older streets around St Paul's Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Geoffrey Field Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work usually takes a few hours for a single window, longer for several.

- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit

- Tell us about any water getting in
- Keep children and pets away from the work area

Why act early in Whitley Wood
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Homes in smaller places like Whitley Wood can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Surface by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
