Facade sealing in Lindfield, done properly

Managing agents and owners in Lindfield ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on coping and flashing joints, window and door perimeters and shopfront frames, and what we’re called in for most is water coming in around window frames and new sealant peeling off old mastic. Most enquiries from Lindfield start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Building work in places the size of Lindfield is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Maintenance after handover

A few simple habits keep the new joints working:

  • Avoid patch repairs on failed facade joints
  • Ask about asbestos in pre-2000 mastic
  • Add perimeter sealant to planned maintenance checks
  • Keep pressure washers away from fresh sealant

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.

Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Damp caused by condensation inside the building
  • Replacing glass or failed glazing units
  • Joints whose design needs changing by the specifier

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.

What we seal

  • Shopfront frames
  • Perimeter joints where frames meet the structure

Questions we are asked in Lindfield

Can you work at a site such as More House Farm Business Centre, by Lindfield?

Yes. Estates, retail parks and business parks around Lindfield, More House Farm Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Can you work on a hospital site such as Princess Royal Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally 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. Work in places the size of Lindfield is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  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.

What we need from you

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

Advice

Signs you need facade sealing in Lindfield

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.

Any of the following is a good reason to get the joints checked over:

  • Air leaks through failed facade joints
  • Hard, chalky sealant that no longer flexes
  • Water coming in around window frames
  • Previous reseals run over old sealant

Building work at universities like University of Sussex (to the south-east of Lindfield) is often timed for the summer, mastic included.

Comparing quotes

  • How the existing material will be dealt with
  • The terms of the workmanship guarantee
  • Is the sealant right for the movement and the substrate?
  • Whether their applicators hold CSCS cards

Our contractor checklist

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Contractors’ notes for Lindfield

Lindfield lies roughly 34 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. A 2-mile radius around Lindfield takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

On a healthcare site such as Princess Royal Hospital, which lies south of Lindfield, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When units on a site such as More House Farm Business Centre (2.9 miles south of Lindfield) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Different surfaces, different methods

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.
