Frames and glazing around Shinfield
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stratfield Saye House (about 4.5 miles south-west) nearby, there’s older building stock in the area around Shinfield as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
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. In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Shinfield
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you are dealing with window mastic to renew ahead of painting and patchy fillers round a sash window, we can put it right, on brick reveals, period & listed homes and timber door frames alike.
Many houses in smaller places like Shinfield have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
We stand behind the work with a one-year guarantee.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It normally takes a few hours for a single window, longer for several. For a job in Shinfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
