Aftercare tips
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Wipe condensation off the frames
- 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, and if anything looks wrong, just call 0345 464 0079 or send us an email.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
About our window mastic in Ilford
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for sealant in the wrong colour for the frame and hard, cracked sealant around windows, across uPVC windows, patio & French doors and timber windows & doors.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Ilford as anywhere.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Do you need window mastic in Ilford?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The most common problems we see are:
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
For an older house near a landmark such as St Alban's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before booking
- How the joint is cleaned and prepared
- How long the guarantee is
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
Windows and doors in Ilford
Historic houses like Valentines Mansion (about 0.9 miles north-west) are a reminder that the area around Ilford has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
For site and facilities teams at buildings such as Winston Way Academy, the mastic around its windows and doors needs looking after like any other building’s. Ilford is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What else we do in Ilford
What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Damp problems in the wall away from the window
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Where we work in Ilford
- Patio & French doors
- uPVC windows
- Composite doors
- Aluminium frames
- Window sills
- Timber windows & doors
What the job involves on each surface
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.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
What affects the quote in Ilford
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- Working hours on commercial sites
- The size of the job
- How easy the joints are to reach
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Why act early in Ilford
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a flat in Ilford, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

FAQs for Ilford
Is Ilford in your area for window mastic?
Yes. We work across London and the South East, and Ilford is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Ilford?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is the new sealant paintable?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a morning for a couple of windows and a door, depending on the size of the job. In a London area like Ilford, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we go round the frames with you and agree the list.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
