Mastic around window and door frames, sills and patio doors for Faringdon, backed by a one-year guarantee. Ask us for a quote.
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
- Gaps where the sill meets the wall
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of frames, longer for a whole house. Parking around Faringdon is generally 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.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- 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.
Getting ready for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Tell us about any water getting in

How we handle window mastic in Faringdon
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on composite doors, patio & French doors and window sills, and people most often call us about cracked sealant at the sill ends and water coming in at the bottom corners of a door.
Homes around Faringdon range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee, whatever its size.

Signs you need window mastic in Faringdon
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
People normally contact us after spotting something like this:
- A bead that doesn’t match the frame
- Rushed sealant from a window installation
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Comparing quotes
- When the joint can take water or movement
- Whether they’re fully insured
- Whether all the old sealant comes out first
- Whether you can choose the colour
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate rooms so frames don’t stay wet inside
- Paint up to the joint, not over it
- Keep timber frames painted
- Keep jet washers away from the mastic
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- The type of sealant required
- Working hours on commercial sites
- The amount of work
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- What’s wrong with the joints now
- The rough size of the job
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Draughts through the window seals rather than the frame
- Faulty window hardware
- Condensation trapped between the panes
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

Frames and glazing around Faringdon
With historic houses such as Buscot Park (about 3 miles north-west) nearby, there’s older building stock in the area around Faringdon 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Faringdon Community College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Local landmarks in Faringdon

Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In an older home around Faringdon, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Your questions about window mastic in Faringdon
Can you do window mastic in Faringdon?
Yes, Faringdon is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
What guarantee comes with window mastic in Faringdon?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Where do you work from?
We work from Crawley. We cover Faringdon and the rest of Oxfordshire, along with the rest of our area.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
