Sand mastic in Spencers Wood
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, brick reveals and period & listed homes, and the jobs we see most are failed mastic on an exposed elevation and gaps between timber frames and stone or brick.
Houses in smaller places like Spencers Wood can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Each job carries a 12-month guarantee.

Spencers Wood homes and the weather
With historic houses such as Stratfield Saye House (about 3.3 miles south) nearby, there’s older building stock in the area around Spencers Wood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to St Michael and All Angels include some older properties, and 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 Reading Green Park station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Surface by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

I let a flat near Reading Green Park station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
What guarantee comes with the work?

Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Clear gutters so water doesn’t pour onto the windows
- Get any rot dealt with first
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What affects the quote in Spencers Wood
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- Mould in or behind the old joints
- How easy the joints are to reach
- How many rooms, windows or areas are involved
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Why act early in Spencers Wood
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. Around Spencers Wood, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
