Facade sealing for commercial buildings in Shellwood Cross

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about old perimeter mastic that has dried out and damp patches beside frames after rain, across shopfront frames, cladding panel joints and stone and brick facade joints. Most enquiries from Shellwood Cross start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Construction in and around smaller places such as Shellwood Cross is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Shellwood Cross, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Your questions answered

Can you keep pace with our programme in Shellwood Cross?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Shellwood Cross too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use.

Does the weather affect the 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. Indoors, the weather is rarely a problem.

Do you seal facades in winter?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Damp caused by condensation inside the building
  • Cracked or spalling substrates that need repair before sealing
  • Specialist high-level access methods

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Surfaces we seal

  • Cladding panel joints
  • Window and door perimeters
  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Stone and brick facade joints

Signs you need facade sealing in Shellwood Cross

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

Things that typically lead to an enquiry:

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

On any site in or around Shellwood Cross, the mastic follows the specification and the programme.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations
  • Who will actually carry out the work
  • Their public liability cover

Questions to ask before you appoint anyone

Building and refurbishing in Shellwood Cross

At about 22 miles from central London, Shellwood Cross is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Shellwood Cross is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Hospital estates such as East Surrey Hospital, 4.8 miles to the east of Shellwood Cross, 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.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • How accessible the joints are

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • Access details, including height

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.

How the job changes by surface

Window and door perimeters

Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.
