How we handle mastic sealing in Peckham
Managing agents and housing associations normally need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have occupiers reporting cold air round windows and leaks at window and door perimeters, we can put it right, on shopfronts below residential blocks, communal entrances and stairwells and communal kitchens and washrooms alike. Facilities teams, main contractors and managing agents in Peckham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
We sign every job 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.

Cost factors for mastic joints
The price varies from site to site. Expect it to depend on:
- The product specified
- Removal of failed or old sealant
- Access and working height
- Whether the work must be split into stages
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Access details, including height
- The postcode of the building
- Clear photographs of the problem areas
- Your programme or deadline
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or send photos by email.
What the job involves on each surface
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.
Common problems we fix in Peckham
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Typical triggers for a call:
- Patchy repairs in mismatched sealant
- No planned programme for sealant
- Window mastic that has split and shrunk
- Water getting in round frames after rain
Churches, halls and community buildings such as All Saints Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- Their plan for phasing and protecting the area
- Who will actually carry out the work
- What level of public liability insurance do they hold?
- What site paperwork they can supply
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. For a job in Peckham, access comes first. Send the building rules and access times with your enquiry.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work

What else we do in Peckham
Peckham: questions and answers
Can work in a care setting near Peckham go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you work at a site such as Astbury Business Park, by Peckham?
Yes. Estates, retail parks and business parks around Peckham, Astbury Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Do you cover Peckham?
Yes. Peckham falls within our area, and the simplest way to start is to ring 01277 525 020 or email drawings and photos.
How long does a typical visit take?
It depends on the scope, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Surfaces we seal
- External wall and movement joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For owners and agents in Peckham
The 2 miles around Peckham include two care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. Our programme follows the access you agree with residents.
If you look after a block within reach of Queens Road Peckham station, which lies north-east of Peckham, frame and balcony mastic can be renewed on one programme. For a school such as John Donne Primary School, perimeter mastic on windows and doors is a holiday job.
