What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a morning for a couple of windows and a door. For a job in Colden Common, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

About our window mastic in Colden Common
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. We work on aluminium frames, window sills and timber windows & doors, and people most often call us about untidy mastic left by window fitters and sealant in the wrong colour for the frame.
Around Colden Common, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
Your job is guaranteed for a year, as with all our work.

Questions from Colden Common
Do you cover smaller places like Colden Common?
Yes, Colden Common is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Shawford station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you guarantee window mastic?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Frames and glazing around Colden Common
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as South Stoneham House (about 4.8 miles south-west) nearby, there’s older building stock in the area around Colden Common as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Shawford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
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.
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, and the work is guaranteed for a year.
What we can’t put right
It helps to know what we can’t do:
- Condensation trapped between the panes
- A sash or casement that will not close properly
- Rotten timber, which needs a joiner first
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Composite doors
- Timber windows & doors
- Patio & French doors
- uPVC windows
- Window sills
- Aluminium frames
When to call us in Colden Common
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
If you look after a building such as Colden Common Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Which sealant they’ll use, and why
- What preparation is included
- How much experience the applicator has
- Whether all the old sealant comes out first
Different surfaces, different methods
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that is what we find.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
