- A frame that has rotted at the joint

How we handle window mastic in Ickleford
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Typical jobs include white mastic on grey or black frames and cracked internal joints between frame and plaster, across timber windows & doors, composite doors and window sills.
In a village or hamlet like Ickleford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same 12-month guarantee.

Common questions in Ickleford
Can you do window mastic in Ickleford?
Yes, Ickleford is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Ickleford?
Yes, Ickleford is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you quote for more than one area?
Yes. Just list everything you need.
Common problems we fix in Ickleford
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Whistling draughts around closed windows
- Mastic that’s falling out in pieces
- Gaps left after new windows were fitted
- Gaps between the frame and the inside reveal
Rented homes near Hitchin station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Whether there’s mould to deal with
- How easy the joints are to reach
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.
Helping us quote
There’s no need for technical detail. Just tell us:
- Where the property is
- How many joints, rooms or windows are involved
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Use gentle cleaners on frames and sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Signs to watch for: 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 happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes most of a day for a typical house, less for a few frames. Somewhere like Ickleford 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

What window mastic looks like in Ickleford
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.
If you look after a building such as Ickleford Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Katharine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
