Window mastic in Hainault, done properly
From a single sill to a whole house of windows, you will get a clear quote before work begins. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. If you have sealant in the wrong colour for the frame and cracked sealant at the sill ends, we can help.
In a smaller place like Hainault, 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.
All our work comes with our 12-month guarantee, wherever you are in Essex.

Surface by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Valentines Mansion (about 2.4 miles south-west) nearby, there’s older building stock in the area around Hainault as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Limes Farm Junior School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Francis of Assisi, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Hainault questions
Can you do window mastic in Hainault?
Yes, Hainault is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you cover smaller places like Hainault?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Are you fully insured?
Yes. We are fully insured.
When to call us in Hainault
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Common reasons people contact us are:
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
Rented homes near Seven Kings station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are. Parking around Hainault 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.
- 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.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Advice
Looking after it afterwards
So the new joints stay in good condition:
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
