Construction mastic in Sutton, done properly
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. We work on brick and block movement joints, cladding and panel joints and window and door perimeters, and what we’re called in for most is inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean. Whoever orders the work in Sutton, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Designing joint widths or choosing the specification (that sits with the designer)
- Joints damaged after sign-off by following trades
- Frame gaps too wide for sealant, which the installer needs to correct
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

The area within 2 miles of Sutton holds several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Sutton. Deliveries are booked and storage is tight, so mastic materials come in as needed.
University estates such as University for the Creative Arts - Epsom, 3.9 miles to the south-west of Sutton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a college such as Sutton College of Learning for Adults, under half a mile south of Sutton, builds or refurbishes, the mastic package typically has to fit around students and staff. Work at a hotel such as Ashling Tara Hotel (to the north of Sutton) tends to be programmed around bookings, mastic included.

Sutton: questions and answers
Can you work at a site such as Kimpton Industrial Park, by Sutton?
Yes, sites like Kimpton Industrial Park are within our area, along with the rest of Sutton. Photos and a short description are enough for a first look.
Can work at a site such as University for the Creative Arts - Epsom fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you cover Sutton?
Yes. We take on work across Sutton, with one number for every area we cover.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Can you work plot by plot or floor by floor?
We work to your programme. Tell us the sequence and we will plan applicators around it.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Looking after the joints
A few simple habits keep the new joints working:
- Protect sealed areas from following trades
- Keep product details for future maintenance
- Allow flexibility for external sealing in damp or cold weather
- Use the product the specification names
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

How the job changes by surface
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and reduces snags.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- The product specified
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
- Any access equipment needed
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- The site address and postcode
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- Any specification or named product
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or send photos by email.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Sutton. Several sites can go on one quote, so there’s one set of paperwork to deal with.
