Blake End Window Mastic
Problem with your window and door frames in Blake End? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Black, perished sealant on frames
- Whistling draughts around closed windows
- Rushed sealant from a window installation
How we handle window mastic in Blake End
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. Typical jobs include cracked or shrunken mastic around the frame and draughts coming in around windows and doors, on composite doors, uPVC windows and aluminium frames.
Somewhere as small as Blake End, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Every job comes with our one-year guarantee.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Do not use solvent cleaners on the joint
- Clean frames with a soft cloth and soapy water
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Why act early in Blake End
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Blake End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What window mastic looks like in Blake End
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Braintree station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In and around Blake End, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the amount of work. Somewhere as small as Blake End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Damp problems in the wall away from the window
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on
