How we handle facade sealing in Sewards End

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with draughts around frames and panels and perimeter joints where frames meet the structure, we can help, whatever the surface. Most enquiries from Sewards End 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.

Construction in and around smaller places such as Sewards End is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. For buildings around smaller places like Sewards End, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Commercial sealant work since 2005
  • Standard and matched colours in many product ranges
  • Work to your specification and the manufacturer’s guidance
  • A fixed quote before work starts

FAQs: Sewards End

Is Ashdon Road Commercial Centre, near Sewards End, within your area?

Yes, sites like Ashdon Road Commercial Centre are within our area, along with the rest of Sewards End. A few photographs and the unit address let us price the work.

Is a smaller place like Sewards End outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

What the job involves on each 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, tooled to shed water.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Combine resealing with other works that need access
  • Brief window cleaners about newly sealed joints
  • Never let anyone seal over old sealant
  • Keep sills, gutters and drainage paths clear

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For a building around Sewards End, 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. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

When to call us in Sewards End

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.

Clients normally get in touch after noticing one or more of the following:

  • Failed seals around shopfront and entrance frames
  • Unsightly perimeter sealant on a visible elevation
  • Gaps between rainscreen or cladding panels
  • Previous reseals run over old sealant

New wings at hospitals like Saffron Walden Community Hospital (no A&E) (1.2 miles west of Sewards End) bring long runs of window and panel joints to seal.
