Our commercial sealant contractors service in CR8
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. Site teams most often ask us about window and door perimeter joints that have cracked open and smeared sealant across finishes from a rushed job, on floor and threshold joints, window and door perimeters and external facade joints.
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.

You will also find Christ Church CofE Primary School (Purley) (0.5 miles north-east), Dollypers Hill (1.8 miles south) and St Swithun's (under half a mile south-west).

Open spaces near Purley include Duppas Hill and Foxley Wood.
Shops, offices and hotels in CR8
In CR8, much commercial sealant work follows refits in shops, offices and hotels in places such as Croydon, Coulsdon and Purley. Visible joints call for a matched colour and a clean tooled finish.
Around the motorway corridors of the South East, business parks and industrial estates are common, and CR8 is part of the area we cover.
Purley: Shopping centres and retail parks such as Whitgift Centre (to the north of Purley) see a steady turnover of shop fits, each leaving joints where colour and finish matter. Premises within reach of Purley station (under half a mile east of Purley) often have busy frontages where joints are seen by everyone passing.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Walls or slabs moving more than any sealant can take
- A failed roof covering or waterproofing membrane
- A dripping trap, valve or pipe behind a fitting
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Note dates and locations of sealant work for future planning
- Check the asbestos register before anyone disturbs old sealant in an older building
- Put external and wet-area joints on a regular inspection round
- Look at the sealant around anything that has been moved or replaced
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to.
Building owners, agents and FMs in CR8
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Different surfaces, different methods
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
Questions about CR8
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Will the building have to shut during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
