Broughton questions
Is Broughton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Broughton for window mastic?
Yes, Broughton is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before any work starts.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you have insurance?
Yes. We are fully insured for every job we do.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit, while a whole house takes longer. You’ll get a timescale with the quote.
Window mastic for homes and businesses in Broughton
Around Broughton we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, patio & French doors and window sills, and people most often call us about mastic that has split away from the wall and mastic that’s falling out in pieces.
Many houses in smaller places like Broughton have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
All our work comes with a 12-month guarantee, wherever you are in Milton Keynes.

Signs you need window mastic in Broughton
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
If you let a flat or house near Woburn Sands station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- The length of the guarantee
- What insurance they hold
- Whether the sealant suits the joint
- Who turns up on the day
Looking after it afterwards
So the new joints stay in good condition:
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Do not aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Parking around Broughton 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Advice
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Faulty window hardware
- A failed sealed unit that has misted up
- A frame that has rotted at the joint
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Window sills
- Aluminium frames
- Timber windows & doors
- Composite doors
- uPVC windows
- Patio & French doors
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Window mastic in Broughton: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Linford Manor (about 3.1 miles north-west) nearby, there’s older building stock in the area around Broughton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Broughton Fields Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Lawrence's Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Local landmarks in Broughton
In Broughton, that means homes and buildings near The Broughton pub and Walton High, among other places. For rail, the closest station is Woburn Sands station, roughly 2.8 miles south-east of the centre. A little further out are Milton Keynes University Hospital (2.4 miles south-west) and National Film and Sci-Fi Museum (2.7 miles west). Open spaces near Broughton include Willen Lake and Blue Lagoon Park.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In an older home around Broughton, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
