Facade sealing in Carter's Clay, done properly

Managing agents and owners in Carter's Clay ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. The enquiries we see most involve damp patches beside frames after rain and failed sealant on precast panel joints, across perimeter joints where frames meet the structure, coping and flashing joints and stone and brick facade joints. A single leaking joint is often how a building in Carter's Clay first comes to us: we look at the rest while we are there and tell you what we find.

For a site near Carter's Clay, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Plan facade sealing alongside redecoration
  • Keep the sealant details on the building file
  • Never let anyone seal over old sealant
  • Ask about asbestos in pre-2000 mastic

Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

Building and refurbishing in Carter's Clay

Rainfall across the South East, Carter's Clay included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

School extensions, at buildings such as Awbridge Primary School, normally run to the summer holidays, mastic included. Hospital estates such as Romsey Community Hospital (4 miles south-east of Carter's Clay) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Carter's Clay is about 4 miles north-west of Romsey, in Hampshire. Looking for facade sealing in Carter's Clay? We can help. Carter's Clay is one of 723 places we cover in Hampshire for facade joints. We also cover Southampton, around 10 miles from Carter's Clay.

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually 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. Rural sites near Carter's Clay may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand

Questions we’re asked in Carter's Clay

Is hospital work, at somewhere like Romsey Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Carter's Clay too far out for you?

No. Places such as Carter's Clay are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.

Can you look at water coming in around a frame?

Yes. Photos help, and you can ring 01277 525 020 or email drawings and photos to arrange a visit. Failed perimeter sealant is a common cause, but not the only one.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed. We don’t remove asbestos-containing materials.

Can staff carry on working while you are here?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

What happens if it’s left?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Around Carter's Clay, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Do you need facade sealing in Carter's Clay?

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

What tends to prompt an enquiry:

  • Failed seals around shopfront and entrance frames
  • Sealant pulling away from frames or panels
  • Staining on stone next to old sealant
  • Water coming in around window frames

With historic properties like Mottisfont Abbey, 1.9 miles north-east of Carter's Clay, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Before you book anyone
