Will you come out to Boyton Cross?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is sand mastic better than silicone for my windows?
We’ll help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.

It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.

What we are called out for in Boyton Cross
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.
Keep an eye out for any of the following:
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
If you let a flat or house near Chelmsford station, any sash windows need sound mastic to keep draughts and rain out.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Look over the window mastic once a year
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Boyton Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Frames and glazing around Boyton Cross
With historic houses such as Hylands (about 3.8 miles south-east) nearby, there’s older building stock in the area around Boyton Cross 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Newlands Spring Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Quotes for sand mastic in Boyton Cross
We quote each job individually. This is what makes a difference:
- The product the joint needs
- Whether there’s mould to deal with
- How many areas need sealing
- Whether the work is at height
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Where the property is
- What’s wrong with the joints now
- Any access issues, like height or stairs
- If someone has resealed it before
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
