Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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, then guaranteed for a year.
About our sand mastic in Gallowstree Common
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on timber door frames, tenement windows and sash and case windows, and people most often call us about gaps round a timber door in stone or brick and silicone on a period window that looks wrong.
Mastic can only go onto a dry, clean joint, so window work in Gallowstree Common is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a 12-month guarantee.

What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Gallowstree Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

With historic houses such as Mapledurham House (about 2.6 miles south-west) nearby, there’s older building stock in the area around Gallowstree Common as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
