Facade sealing around Peckham: points for this area

The area within 2 miles of Peckham holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Site traffic in Peckham falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.

When units on a site such as Astbury Business Park (under half a mile north-east of Peckham) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Extensions at sites like Maudsley Hospital (1.2 miles west of Peckham) typically sit beside working departments, and the mastic follows strict access rules.

Peckham is about 2 miles south-east of London, in Greater London. Any commercial site in Peckham is covered, for single jobs and planned programmes alike. Peckham is one of 764 places in Greater London on our list for facade joints.

Postcode districts covered here: SE15, SE14 and SE5 for facade joints. Buildings on Rye Lane, Relf Road and Mona Road are within our area for facade joints. Main routes into Peckham include the A2215, which helps when planning parking and deliveries for the job. Nearby places we also cover include Nunhead (1 mile south-east), Telegraph Hill (1 mile south-east), South Bermondsey (1 mile north), Surrey Canal (1 mile north-east) and East Dulwich (1 mile south-west). Further afield, our area takes in City of Westminster (5 miles north-west), Marylebone (5 miles north-west), Kensington (6 miles west), St Pancras (4 miles north-west), Shoreditch (4 miles north) and Walthamstow (8 miles north).

Local landmarks in Peckham

Around Peckham, our work takes us to commercial buildings near Brimmington Park, The St Thomas the Apostle College and The Kentish Drovers pub. Peckham has its own railway station: Queens Road Peckham station. A little further out are Peckham Platform (less than half a mile north-west) and Southwark Adult Education Institute (under half a mile east). The countryside around Peckham includes St. James's Park Lake and Knight's Hill.

How we handle facade sealing in Peckham

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. If you’re dealing with air leaks through failed facade joints and leaks at window and door perimeters, we can put it right, on cladding panel joints, stone and brick facade joints and shopfront frames alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Peckham, preparation and product choice get the time they need.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  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. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Send your site hours and access windows

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Don’t wait for a second leak before calling
  • Confirm the survey covers external sealants in older buildings
  • Brief window cleaners about newly sealed joints
  • Never let anyone seal over old sealant

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Joints whose design needs changing by the specifier
  • Replacing glass or failed glazing units
  • Arranging specialist high-level access, which is planned with the client

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Where we work in Peckham

Cost factors for facade joints

Before we quote, we look at:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • How much there is to seal

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email us.

Common problems we fix in Peckham

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

If one of these sounds familiar, it’s time for a closer look:

  • Cold air coming in at window perimeters
  • Cladding panel joints that have opened up
  • New sealant peeling off old mastic
  • Perimeter sealant that has split or peeled away

Hotels like Peckham Rooms Hotel (to the north of Peckham) rarely close for long, so refurbishment mastic is phased floor by floor.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • How they handle RAMS and site documents
  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Your questions answered

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Can you work at a site such as Astbury Business Park, by Peckham?

Yes, sites like Astbury Business Park are within our area, along with the rest of Peckham. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you work in cold or wet weather?

Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things as the work goes on.

Will you quote for a small job?

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.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can call 01277 525 020 or email us to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

How the job changes by surface

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch without tearing.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
