How we handle mastic sealing in Gossops Green
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal entrances and stairwells and communal kitchens and washrooms, and what we are called in for most is occupiers reporting cold air round windows and failed external movement joints. Facilities teams, main contractors and managing agents in Gossops Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Places the size of Gossops Green usually have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Water coming in from the roof or rainwater goods
- Misted or failed double-glazed units
- Asbestos-containing sealant, which we don’t remove
If in doubt, phone 01277 525 020 or email us and we will say what we think.
Surfaces we seal
- Communal kitchens and washrooms
- External wall and movement joints

FAQs: Gossops Green
Can you quote for a block close to Ifield station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Can work in a care setting near Gossops Green go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you cover Gossops Green?
Yes. Gossops Green is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email the details over.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Why deal with it now?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Planned mastic for Gossops Green portfolios
There are two care or nursing homes within about 2 miles of Gossops Green. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. Gossops Green is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Landlords with units on estates such as Denvale Trade Park, 1.1 miles to the east of Gossops Green, can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Ifield station, which lies west of Gossops Green, frame and balcony mastic can be renewed on one programme. Churches, halls and community buildings such as St Peter's are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- List the paperwork your organisation requires when you send details
- Encourage occupiers to report problems at frames
- Share the asbestos register when you send details
- Keep a record of when each building was resealed
Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
