Window mastic in Headington Hill
Around Headington Hill we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We’re often asked to deal with hard, cracked sealant around windows and sealant in the wrong colour for the frame, across uPVC windows, timber windows & doors and aluminium frames.
Houses in smaller places like Headington Hill can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
All our work is covered by a one-year guarantee, wherever you are in Oxfordshire.

How it works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. Parking around Headington Hill is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Plan for the work area to be out of bounds to pets and children

Advice
Windows and doors in Headington Hill
The South East is one of 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 Holywell Manor (about 1 mile west) nearby, there’s older building stock in the area around Headington Hill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Oxford station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Cheney School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as All Saints' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
We also work for property managers and facilities teams. We can quote a run of properties together.
Surface by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
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.
What sealant work can’t fix
It helps to know what we can’t do:
- A door that needs adjusting, rehanging or new seals
- Damp problems in the wall away from the window
- Rotten timber, which needs a joiner first
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
Surfaces we seal
- Aluminium frames
- Composite doors
- Patio & French doors
- uPVC windows
- Window sills
- Timber windows & doors
DIY versus a professional finish
Not every job suits DIY: 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’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
