How we handle window mastic in Littlemore
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for black, perished sealant on frames and untidy mastic left by window fitters, on patio & French doors, timber windows & doors and aluminium frames.
In smaller places like Littlemore, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Windows and doors in Littlemore
Historic houses like Holywell Manor (about 2.7 miles north) are a reminder that the area around Littlemore has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Radley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Mary and St Nicholas include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a morning for a couple of windows and a door. Parking around Littlemore is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
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.
Landlords, agents and businesses in Littlemore
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
For anyone letting property in or around Littlemore, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Walk round the house once a year and look at the joints
- Don’t aim a pressure washer at the joints
- Wash the frames with mild soapy water
Most silicone sealants won’t take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Littlemore questions
I let a flat near Radley station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover Littlemore for window mastic?
Yes. Our work covers London and the South East, and Littlemore is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Is the new sealant paintable?
Most silicone can’t be painted. Let us know beforehand, and we will use a paintable product where it suits.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
When to call us in Littlemore
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The most common problems we see are:
- A bead that doesn’t match the frame
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
If you look after a building such as Emmanuel Christian School, its window and door frames need their mastic kept sound, just like a home’s.

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- The rough size of the job
- Access, such as stairs, a lift or height
- The address or postcode of the job
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
