For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit

Advice
Sand mastic in Little Marlow
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you’re dealing with draughty sash windows at the surround and weathered mastic on the most exposed windows, we can help.
Around Little Marlow, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All our work comes with our 12-month guarantee.

What we’re called out for in Little Marlow
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
In the older streets around Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Frames and glazing around Little Marlow
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. Historic houses like Cliveden (about 2.9 miles south-east) are a reminder that the area around Little Marlow has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Why act early in Little Marlow
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a small place like Little Marlow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured.
