How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go. Planning a London job such as one in Shortlands starts with access. Give us the hours we can be on site and we will schedule to suit.
- We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Getting the site ready
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- Point out any areas we must not close

Commercial sealant contractors for commercial buildings in Shortlands
We’ve applied sealant on commercial sites for over 20 years: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on external facade joints, movement joints in walls and floors and floor and threshold joints, and the failures we are asked to look at most are expansion joints with the sealant torn out and water staining near frames, panels or ceilings. Most enquiries from Shortlands start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
We price commercial jobs in Shortlands from photos, drawings or a site visit, and the scope is set out in writing.
For managing agents and FMs looking after premises in Shortlands, access is typically the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Quoting for work in Shortlands
A fixed quote reflects the actual work. It takes account of:
- Quantities, in metres or numbers
- The size and state of each joint
- Whether the work must be split into stages
- Which sealant the job calls for
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Access details, including height
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- The site address and postcode
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.
Nearby places to Shortlands
More services for Shortlands
Different surfaces, different methods
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.
Common problems we fix in Shortlands
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Clients usually get in touch after noticing something like this:
- Gaps behind commercial kitchen worktops and sinks
- Weathered facade sealant that no longer flexes
- Window and door perimeter joints that have cracked open
- Black mould through washroom sealant that won’t clean off
On a business park such as Chartwell Business Centre, 1.4 miles east of Shortlands, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
Before you book anyone
- Health and safety accreditation such as CHAS
- Will RAMS and insurance details be available?
- How joint depth will be controlled
- What level of public liability insurance do they hold?
After the work
Once the work is signed off, a little attention goes a long way:
- Keep abrasive pads and scrapers off resealed joints
- Have extract fans checked so wet areas dry out
- Look at the sealant around anything that has been moved or replaced
- Keep a record of which joints were resealed and when
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest. We can assess the lot and suggest what to do now and later.
Questions about Shortlands
Is Chartwell Business Centre, near Shortlands, within your area?
Yes. Estates, retail parks and business parks around Shortlands, Chartwell Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Must a hotel around Shortlands close while you work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Which site documents can you send us?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Can you handle sealant work across several sites?
Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Why deal with it now?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Getting scaffold, permits or access booked in Shortlands takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
