About our window mastic in Bulphan
Homes in Bulphan have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, timber windows & doors and composite doors, and common reasons people get in touch are cracked internal joints between frame and plaster and gaps left after new windows were fitted.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Bulphan as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
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 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 confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.

Window mastic in Bulphan: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. 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.
As a London address, Bulphan can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Bulphan Church of England Academy, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Bulphan
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out 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.
Landlord and commercial work in Bulphan
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Bulphan and across Greater London. Several sites can go on one quote, and we’re fully insured.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Ventilate rooms so frames do not stay wet inside
- Don’t aim a pressure washer at the joints
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.

Do you need window mastic in Bulphan?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people generally mention when they call are:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Mastic that’s falling out in pieces
- Cracked or shrunken mastic around the frame
If you let a flat or house near West Horndon station, renewing tired window mastic between tenants heads off draught and damp complaints.
