With the paperwork done, the joints are worked through in the order agreed with your site contact. Planning a London job such as one in Angel starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.

New build and refits around Angel
The area within 2 miles of Angel holds plenty of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. As part of Greater London, Angel is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
On a campus such as Paris Dauphine University - London Campus, less than half a mile west of Angel, new teaching buildings and residences are normally built and refurbished around the academic year. New wings at hospitals like Moorfields Eye Hospital (City Road campus), 0.8 miles south-east of Angel, bring long runs of window and panel joints to seal. For contractors at a college like City and Islington College, less than half a mile south-east of Angel, perimeters and internal sealant are timed for the holidays.
Angel is about 1 mile north-east of St Pancras, in Greater London. Businesses, contractors and managing agents in Angel can call on us for facade joints. Our Greater London coverage takes in 764 places.
Anyone looking for facade sealing in N1, N1P and EC1V gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

What happens if it’s left?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

- Work carried out by CSCS-carded applicators

Take a look at what affects the cost or our accreditations and insurance.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email drawings and photos with what you know.
Questions about Angel
Could you schedule work at a campus like Paris Dauphine University - London Campus for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work at a site such as Roman Way Industrial Estate, by Angel?
Yes, sites like Roman Way Industrial Estate are within our area, along with the rest of Angel. Send details of the unit and the work through our quote form for a quick quote.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you cover Angel?
Yes. Angel falls within our area, and you can call 01277 525 020 or email us to get started.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Investigate damp beside windows promptly
- Never let anyone seal over old sealant
- Walk the elevations once or twice a year
- Keep sills, gutters and drainage paths clear
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. 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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
