Landlords, agents and businesses in South Earlswood
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Older cottages and farmhouses around South Earlswood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we’re called out for in South Earlswood
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
Homes close to Christ the King include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- What insurance they hold
- Whether the sealant suits the joint
- The length of the guarantee
- What the cure time is
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Somewhere as small as South Earlswood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Let us know about parking restrictions
