How many windows can you do in a day?

What should I tell you?

Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Window mastic for homes and businesses in Shotover Hill
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on uPVC windows, composite doors and aluminium frames, and people most often call us about sealant in the wrong colour for the frame and mastic that has split away from the wall.
In a smaller place like Shotover Hill, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Our work is backed for twelve months, in Shotover Hill and everywhere else we cover.

Frames and glazing around Shotover Hill
With historic houses such as Holywell Manor (about 2.4 miles west) nearby, there’s older building stock in the area around Shotover Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Oxford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Wood Farm Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Shotover Hill is about 2 miles east of Oxford, in Oxfordshire. From the centre of Shotover Hill to the outskirts, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels.

Different surfaces, different methods
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why it’s worth doing now in Shotover Hill
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Around Shotover Hill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Aftercare tips
A little care helps the new joints last. We recommend:
- Do not use solvent cleaners on the joint
- Don’t aim a pressure washer at the joints
- Repaint timber before it’s bare
- Look round the frames every year or so
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. A visit to Shotover Hill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- 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.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
