Window & door mastic in Shepherd's Green, Oxfordshire
Professional window mastic in and around Shepherd's Green, with old sealant always removed completely and a 12-month guarantee.
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Look round the frames every year or so
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
- Keep paint and stain on wooden frames in good order
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Window mastic in Shepherd's Green
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on patio & French doors, timber windows & doors and composite doors, and people most often call us about gaps left after new windows were fitted and a bead that doesn’t match the frame.
Mastic can only go onto a dry, clean joint, so window work in Shepherd's Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Your job is guaranteed for a year, as with all our work.

Do you need window mastic in Shepherd's Green?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
If you can see any of these, it’s time to have the joints looked at:
- Hard, cracked sealant around windows
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Leaking joints at the ends of sills
Managing a site like Peppard Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere like Shepherd's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.

FAQs for Shepherd's Green
Will you come out to Shepherd's Green?
Yes. Shepherd's Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Henley-On-Thames station?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Where a wall is exposed, as many are in small places like Shepherd's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Shepherd's Green homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Greys Court (about 0.7 miles east) nearby, there’s older building stock in the area around Shepherd's Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Henley-On-Thames station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
