Facade sealing across Margaretting

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Surface by surface

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, not the framing or glazing itself.

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

Facade sealing in Margaretting, done properly

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. The enquiries we see most involve new sealant peeling off old mastic and failed seals around shopfront and entrance frames, across window and door perimeters, shopfront frames and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Margaretting, that means joint design, primers and backing rod as standard.

Construction in and around smaller places such as Margaretting 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.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

General trades versus a 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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed
  • Report water ingress at frames as soon as it shows
  • Add perimeter sealant to planned maintenance checks

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

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones behind the facade.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Damaged frames that need replacing
  • Water getting in through cracked render or porous masonry
  • Work on the window or framing system itself

If in doubt, phone 01277 525 020 or email the details over and we will say what we think.

What we seal

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

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Whether you’re 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. We can agree access arrangements and keyholder contacts beforehand.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Margaretting are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Share the asbestos register for older buildings
  • Move anything stored against the joints
  • Point out parking and an unloading spot

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Common questions from Margaretting clients

Is Margaretting too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Widford Industrial Estate, by Margaretting?

Yes. Estates, retail parks and business parks around Margaretting, Widford Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Sites and facades in and around Margaretting

Margaretting is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Central London is about 26 miles from Margaretting. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

For contractors at a school such as Anglo European School, sealing has to be finished before term starts. New wings at hospitals like Chelmsford and Essex Hospital, 2.8 miles north-east of Margaretting, bring long runs of window and panel joints to seal. Recladding or extending a unit at a site like Widford Industrial Estate (to the north-east of Margaretting) brings panel joints and frame perimeters into the programme.
