Construction mastic for commercial buildings in Oakthorpe Park
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Oakthorpe Park, send drawings through our quote form, or phone or email us to talk it through. Site teams most often ask us about inconsistent sealant finishes from plot to plot and sealant knocked or painted over by other trades, on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints. Looking for mastic applicators who cover Oakthorpe Park? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Frame gaps too wide for sealant, which the installer needs to correct
- Joint design decisions that belong to the architect or engineer
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal

Why it’s worth doing now in Oakthorpe Park
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. We cut out and redo the joint properly. In Oakthorpe Park, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Why appoint us
- Work carried out by CSCS-carded applicators
- Clear, fixed quotes
- Coloured sealants to suit the setting, where available
- Joints cleaned back to sound surfaces

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
How the job changes by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
Questions we’re asked in Oakthorpe Park
Will you take on work at estates like St. George's Industrial Estate, close to Oakthorpe Park?
Yes. Our area takes in Oakthorpe Park and its surroundings, with estates and business parks such as St. George's Industrial Estate included. Photos and a short description are enough for a first look.
Could you schedule work at a campus like American University in London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you take on mastic snagging only?
Yes. We can work through a mastic snag list area by area before handover.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and we clear our waste as we work. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we will be in
Get a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email the details over with what you know.
