Construction mastic for Tyburn sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. In Tyburn, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Drawings, the sealant specification and your programme come to us for pricing.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- Explain the parking and delivery arrangements
- Let us know about inductions and permits

Construction mastic in Tyburn, done properly
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Site teams most often ask us about internal caulk splitting as the building dries out and perimeter gaps outside the sealant’s range, on window and door perimeters, internal decorators’ caulk and brick and block movement joints. For commercial sealant work in Tyburn, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Every London site, Tyburn included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

After the work
Once the work is signed off, a little attention goes a long way:
- Stick to the specified sealant rather than a generic substitute
- Release areas for mastic once other trades have finished in them
- Check frame gaps are within the sealant’s range before sealing
- Keep scrapers and abrasive pads off new beads
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
When to call us in Tyburn
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
Common reasons buildings call us in:
- Internal caulk splitting as the building dries out
- External joints sealed in damp or cold conditions that are now failing
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
On a campus such as BPP University, under half a mile west of Tyburn, new teaching buildings and residences are typically built and refurbished around the academic year.
Comparing quotes

- Whether old or failed sealant will be cut out, not overlaid
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
Why act early in Tyburn
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites. Called in at the end, the same issues surface during handover. Getting scaffold, permits or access booked in Tyburn takes effort, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why appoint us
- Standard and matched colours in many product ranges
- One number for every site we cover
- Colours confirmed for the specified product
- Matching to RAL references, product permitting

Mastic packages on Tyburn sites
The ULEZ covers the whole of Greater London, Tyburn included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Tyburn holds plenty of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Projects at colleges like London College of Fashion (to the east of Tyburn) tend to run to term dates, so the mastic is planned tightly. Hotel extensions and refits, at places such as Parkwood Hotel, under half a mile to the north-east of Tyburn, normally run between busy periods, so the sealing is squeezed into short windows.

Site staff or a sealant specialist?
Paperwork matters too. 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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Tyburn: questions and answers
Will you plan work around the academic year at somewhere like BPP University?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you cope with the access rules in a London building?
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. The ULEZ covers the whole of Greater London, which we allow for
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Do you install fire-rated sealant as part of a package?
It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.
