Facade sealing for commercial buildings in Little Chesterford

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. If you have failed seals around shopfront and entrance frames and facade joints cracked through the middle, we can put it right, whatever the surface. A single leaking joint is often how a building in Little Chesterford first comes to us: we look at the rest while we’re there and tell you what we find.

Sites around smaller places like Little Chesterford can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the quote is worked out

These are the things that shape the price:

  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Access and working height

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

Questions we’re asked in Little Chesterford

Can you work around term dates at a campus such as St Mark's College?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Little Chesterford off your patch?

Not at all. Little Chesterford is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

What about RAMS and site documents?

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

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

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.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Little Chesterford are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  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 and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Let building users know which areas are affected
  • Flag any permit to work we will need
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Signs you need facade sealing in Little Chesterford

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

Look out for the following:

  • Cladding panel joints that have opened up
  • Old perimeter mastic that has dried out
  • New sealant peeling off old mastic
  • Water coming in around window frames

School extensions, at buildings such as Great Chesterford Church of England Primary Academy, normally run to the summer holidays, mastic included.

What to look for in a quote

  • Their approach to joint depth and backing
  • Their public liability cover
  • How the joint faces will be prepared and primed
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Specialist high-level access methods
  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.

Joints and surfaces we work on

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

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

New build and refits around Little Chesterford

Rainfall across the South East, Little Chesterford included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Little Chesterford is about 40 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Saffron Walden Community Hospital (no A&E) (to the south-east of Little Chesterford) bring long runs of window and panel joints to seal. Projects at colleges like St Mark's College (to the south of Little Chesterford) tend to run to term dates, so the mastic is planned tightly.

Little Chesterford is about 3 miles north-west of Saffron Walden, in Essex. If you are looking for facade sealing in Little Chesterford, we can help. We work across 644 places in Essex. We also cover London, some 40 miles away.

Work on facade joints is covered throughout CB10. We also cover Littlebury (1 mile south), Little Walden (2 miles east), Audley End (2 miles south), Saffron Walden (3 miles south-east) and Wendens Ambo (3 miles south) for facade joints. Bigger towns within reach include Great Dunmow (14 miles south-east), Stansted Mountfitchet (10 miles south), Elsenham (10 miles south), Church End (14 miles south-east), Thaxted (9 miles south-east) and Newport (5 miles south).

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
