How we handle facade sealing in Gay Street
Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters, and what we’re called in for most is patch repairs that keep failing and facade joints cracked through the middle. For commercial sealant work in Gay Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Conversions of older rural buildings near smaller places such as Gay Street bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How a job runs
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Gay Street, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.

- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Confirm the product named in the specification
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work

What happens if it’s left?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Halls, stores and units around places like Gay Street may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

New build and refits around Gay Street
Gay Street sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Gay Street is about 40 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
For contractors refurbishing units at places like Broomers Hill Business Park (1.4 miles west of Gay Street), the mastic covers cladding panels, roller-door and window perimeters. Projects at colleges like Brinsbury College, 1.4 miles north-west of Gay Street, tend to run to term dates, so the mastic is planned tightly.
Gay Street is about 9 miles south-west of Horsham, in West Sussex. Businesses, contractors and managing agents in Gay Street use us for work on facade joints, as part of our coverage of West Sussex.

Questions we’re asked in Gay Street
Will you plan work around the academic year at somewhere like Brinsbury College?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Gay Street too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Surface by surface
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
- Walk the elevations once or twice a year
- Never let anyone seal over old sealant
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
Common problems we fix in Gay Street
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
Clients typically get in touch after noticing something like this:
- Perimeter sealant that has split or peeled away
- Perimeter joints where frames meet the structure
- Old perimeter mastic that has dried out
- Discoloured or dirty facade joints
With historic properties like Old Place Manor (2.4 miles south-west of Gay Street) in the area, refurbishment work often meets old masonry that needs compatible sealants.
