About our window mastic in Emerson Park

To get one, ring 0345 464 0079 or send us an email with the number of frames and any access details. If you are dealing with draughty joints inside around the window and cracked sealant at the sill ends, we can put it right, on window sills, aluminium frames and patio & French doors alike.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.

What we are called out for in Emerson Park
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Look out for these signs:
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Mastic that is falling out in pieces
If you live in an older home near All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.
What to look for in a quote
- Which colour the sealant will be
- Whether they’re fully insured
- Is the old sealant removed completely?
- When the joint can take water or movement
DIY versus a professional finish
If you are set on DIY, put the effort into 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What else we do in Emerson Park
Windows and doors in Emerson Park
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Hare Hall (about 1.2 miles north-west) are a reminder that the area around Emerson Park 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.
As a London address, Emerson Park can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Nelmes Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Surface by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
The process
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work generally takes a morning for a couple of windows and a door. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Mention if the joints have been sealed before

Advice
Why it’s worth doing now in Emerson Park
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Emerson Park, the repair is bigger than a sealant job.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Common questions in Emerson Park
Is Emerson Park in your area for window mastic?

Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
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.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
