Construction mastic in Shirley, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve mastic snags holding up handover and sanitary sealant damaged by following trades, across cladding and panel joints, sanitary and kitchen joints and brick and block movement joints. Most enquiries from Shirley 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.
Around Shirley, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Use the product the specification names
- Allow flexibility for external sealing in damp or cold weather
- Note which sealant went where at handover
- Ask cleaners to use soft cloths around fresh sealant
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.
One unsealed frame can let water into finished internal areas. That normally means redoing finishes in a completed area. Checking perimeters before internal finishes go on avoids it.
Construction mastic in Shirley: the local picture
The ULEZ covers the whole of Greater London, Shirley included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are a number of hotels within about 2 miles of Shirley. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When a college such as Croydon College (1.8 miles west of Shirley) builds or refurbishes, the mastic package usually has to fit around students and staff. School extensions, at buildings such as Oasis Academy Shirley Park, normally run to the summer holidays, mastic included. Older buildings in the area around Shirley, such as Addington Palace (1.7 miles south of Shirley), need care when sealed: the product has to suit soft or historic materials.
Shirley is about 2 miles north-east of Croydon, in Greater London. We send applicators to Shirley for mastic packages, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Sites around London have their own page, roughly 8 miles from Shirley.
Commercial sites across CR0, SE25 and CR9 are covered for mastic packages. Buildings on Poppy Lane, Homer Road and Craven Road are within our area for mastic packages. You will find Shirley on or near the A232. We also cover Monks Orchard (1 mile north), Shirley Oaks (1 mile west), Addiscombe (1 mile west), Ashburton (1 mile north-west) and Woodside (1 mile north-west). Bigger towns within reach include London (8 miles north), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (10 miles north-west), St Pancras (10 miles north) and Shoreditch (10 miles north).

A little further out are Crystal Palace Museum (2.8 miles north) and St George's Walk (2 miles west). Open spaces near Shirley include Duppas Hill and Bramley Bank.
Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area.
FAQs: Shirley
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Could you schedule work at a campus like Croydon College for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work so we usually switch to internal work when that happens.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
