About our facade sealing in Chase Cross

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We plan for that and keep you updated. If you are dealing with failed sealant on precast panel joints and damp patches beside frames after rain, we can put it right, whatever the surface. Whoever orders the work in Chase Cross, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Maintenance after handover

Once the work is signed off, these steps help:

  • Add perimeter sealant to planned maintenance checks
  • Avoid harsh cleaners on facade sealant
  • Never let anyone seal over old sealant
  • Investigate damp beside windows promptly

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Building and refurbishing in Chase Cross

Chase Cross has a number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Chase Cross included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

Recladding or extending a unit at a site like Rom Valley Retail Park (to the south of Chase Cross) brings panel joints and frame perimeters into the programme. For contractors at a college like Havering Technical College, 2.3 miles to the east of Chase Cross, perimeters and internal sealant are timed for the holidays. On a healthcare site such as Victoria Hospital, 1.6 miles south of Chase Cross, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Chase Cross is about 2 miles north of Romford, in Greater London. Looking for facade sealing in Chase Cross? We can help, as we do across Greater London. Chase Cross is one of 764 places in Greater London on our list. For work in that direction, see our London page.

Why it’s worth doing now in Chase Cross

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Getting scaffold, permits or access booked in Chase Cross takes effort, so it makes sense to deal with every failing joint while access is in place.

There’s no price list, since every building and every scope is different. Call for a quote.

What you get with us

  • Joints cleaned back to sound surfaces
  • Commercial sealant work since 2005
  • Coloured sealants to suit the setting, where available
  • Health and safety: CHAS accredited

See our cost guide and our accreditations.

How the quote is worked out

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

  • How much there is to seal
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Distance, for remote addresses

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

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

  • The product your specification calls for
  • The site address and postcode
  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available

To get a fixed quote, ring 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Planning a London job such as one in Chase Cross starts with access. Give us the hours we can be on site and we will schedule to suit.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Common questions from Chase Cross clients

Could you schedule work at a campus like Havering Technical College for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Would you work within a site like Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

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. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Water getting in through cracked render or porous masonry
  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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