Construction mastic in Petersham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frames fitted out of tolerance
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Window and door perimeters
- Floor and skirting junctions
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
- Cladding and panel joints
About our construction mastic in Petersham
We work to the specification and the programme, not to habit. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. If you’re dealing with perimeter gaps outside the sealant’s range and bath and shower joints scraped during the final clean, we can help, on cladding and panel joints, sanitary and kitchen joints and floor and skirting junctions alike. Most enquiries from Petersham 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.
Every London site, Petersham included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites typically need booked deliveries and a plan for where materials go.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What else we do in Petersham
Mastic packages on Petersham sites
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Petersham. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Petersham holds a good number of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Hotel extensions and refits, at places such as The Petersham Hotel, which lies north-east of Petersham, normally run between busy periods, so the sealing is squeezed into short windows. Extensions at sites like Cassel Hospital (to the south of Petersham) normally sit beside working departments, and the mastic follows strict access rules.
Petersham is about 1 mile south of Richmond, in Greater London. We send applicators to Petersham for mastic packages. Petersham is one of 764 places we cover in Greater London. For work in that direction, see our London page.

Around Petersham

Do you need construction mastic in Petersham?
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
Things that typically lead to an enquiry:
- A mastic package split between trades with no clear owner
- Old sealant on a refurbishment that needs stripping before new work
- Frame perimeters left unsealed or poorly sealed
- Caulk cracking where joints are moving more than expected
Projects at colleges like Richmond-upon-Thames College, 1.7 miles to the west of Petersham, tend to run to term dates, so the mastic is planned tightly.
What your quote should include
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
- The terms of the workmanship guarantee
- Will CSCS-carded applicators be on site?
Petersham: questions and answers
Would you work within a site like Cassel Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is St. George's Industrial Estate, near Petersham, within your area?
Yes. We cover Petersham and the area around it, including industrial estates, business parks and retail parks such as St. George's Industrial Estate. Photos and a short description are enough for a first look.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What do you charge?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
What joints do you seal on a new build?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can the building stay open while you work?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Surface by surface
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
Quotes
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
