FAQs: Elstree
Could you schedule work at a campus like Middlesex University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Elstree too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Facade sealing in Elstree
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and failed sealant on precast panel joints, across window and door perimeters, coping and flashing joints and stone and brick facade joints. Whoever orders the work in Elstree, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a site near Elstree, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Elstree need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Confirm the product named in the specification
- Warn occupants and staff about the work
- Agree which areas must stay open
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Leave it or put it right?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Around Elstree, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Facades, frames and programmes in Elstree
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. A 2-mile radius around Elstree takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
New units and refits on sites such as Lismirrane Industrial Park, 0.7 miles to the west of Elstree, need their panel and perimeter joints sealed to the specification.

Work at a hotel such as Manor Hotel, 0.5 miles south-east of Elstree, tends to be programmed around bookings, mastic included.

Surface by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.
Precast concrete panels
Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair first.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Arranging specialist high-level access, which is planned with the client
- Installing or repairing glazing systems
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Stone and brick facade joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Shopfront frames
- Window and door perimeters
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Plan facade sealing alongside redecoration
- Keep sills, gutters and drainage paths clear
- Don’t wait for a second leak before calling
- Note when each elevation was last resealed
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.
