How we handle facade sealing in Wych Cross

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you’re dealing with perimeter joints where frames meet the structure and cladding panel joints that have opened up, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Wych Cross tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Wych Cross can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Contractors’ notes for Wych Cross

Rainfall across the South East, Wych Cross included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Wych Cross is about 30 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.

Historic houses such as Standen, 3.2 miles to the north-west of Wych Cross, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. On a healthcare site such as Queen Victoria Hospital, which lies north of Wych Cross, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Wych Cross is about 4 miles south-east of East Grinstead, in East Sussex. Wych Cross sits inside our coverage and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Report water ingress at frames as soon as it shows
  • Share access with other external trades
  • Note when each elevation was last resealed
  • Clear debris that holds water against joints

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. Smaller jobs around Wych Cross can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Arrange parking or a loading space
  • Send any specification or drawings in advance
  • Send your site hours and access windows

Related advice

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Your questions answered

Do you cover business parks and estates near Wych Cross, such as Forest Row Business Park?

Yes. We cover Wych Cross and the area around it, including industrial estates, business parks and retail parks such as Forest Row Business Park. Photos and a short description are enough for a first look.

Is Wych Cross too small for you to travel to?

Not at all. Wych Cross is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Do you replace windows or glass?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.

Why act early in Wych Cross

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Converted and older buildings near places like Wych Cross tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Access often affects the price as much as the sealing: 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.

When to call us in Wych Cross

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Unsightly perimeter sealant on a visible elevation
  • Draughts around frames and panels
  • Weathered facade joints that have lost their grip

For a contractor at a hotel such as Ashdown Park Hotel and Country Club, less than half a mile east of Wych Cross, the mastic often has to be finished before a reopening date.
