Exterior building envelope · cleaning, repair & restoration
Building envelope cleaning, repair and restoration by vetted, insured specialists.
From a stained elevation to full render and masonry restoration across a managed block, one vetted specialist handles the lot, usually without a six month scaffold. RAMS and insurance before anyone mobilises, and a fixed price that is still the price on the invoice.

One vetted specialist for the whole envelope, not just the clean
A clean is often where it starts. The real work is what is underneath, cracked render, failing pointing, spalling concrete, tired balconies. One specialist handles the lot in one programme, on one quote, so you are not managing three contractors and three mobilisations. From a single elevation to a full restoration across a managed block.

Two things our specialists will not do
01
Put up a scaffold you don't need
On most buildings under fifteen storeys, rope access does the same job for a fraction of the cost and without closing your forecourt for two months. When a scaffold genuinely is the right call we will say so. But one never goes up just to pad the bill. You get an honest read on access at survey, in writing.
02
Quote you a day rate
Day rates reward slow work and turn every weather delay into your problem. Our specialists do not use them. After a survey you get one fixed, itemised price, and that is the number on the final invoice unless you ask us in writing to change the scope. Nothing for the board to query later.
What we cover
A facade rarely has just one problem, and the clean is rarely the expensive bit. The value is in the repair and restoration underneath, and one matched specialist covers it all on one quote, from a single elevation to a full envelope refurbishment on a managed block.
If your job needs a trade we are not best at, we will tell you and point you to someone who is.
01
Render and EWI repair
Cracks, blown sections and delaminating external wall insulation made good and recoated. On a managed block this is the five figure job, and the one we are built for.

02
Stone and masonry restoration
Repointing, stone repair and brick replacement on period and listed frontages, to a spec a conservation officer will sign off.

03
Concrete and balcony repair
Spalling concrete, exposed rebar and tired balcony soffits made good and protected, the work that keeps fragments off the pavement and the building safe.

04
Facade cleaning
DOFF steam and soft washing for stone, brick and render. The specialist lifts algae, carbon staining and the green streaking leaseholders complain about, without blasting the substrate to bits. Often where it all starts.

05
Rope access and MEWP
IRATA technicians for the work scaffolding would make slow and expensive. When a MEWP or tower is the smarter option, we use that instead.

Coatings and protection
Anti carbonation coatings, water repellents and anti graffiti systems that buy you years before the next visit is due.

Planned maintenance
A cleaning and inspection cycle across a block or a whole portfolio, so the facade never gets bad enough to become a Section 20 conversation.

The sectors we cover
Specified, scheduled and documented for professional buyers. Each sector has its own page.
Not sure whether the building needs a clean, a repair, or just leaving another year? Send a photo of the elevation and a surveyor will tell you straight, even if the honest answer is you do not need us yet.
We handle your building envelope end to end. Three steps, no scaffold of paperwork to wade through first.
01
Send the building, not a brief
A photo of the elevation or a line about the block is enough. A surveyor reads it and tells you whether it is a clean, a repair, or something to leave another year.
02
We put a vetted specialist on it
An IRATA certified, insured specialist who genuinely covers your area is assigned, checked by us on tickets, cover and recent work before any work starts.
03
One fixed price, on your terms
The specialist surveys, prices a defined scope as a fixed figure, and sends the RAMS and insurance before anyone goes up. Your details are never sold on.
Safety and accreditations
Working at height is the discipline we vet for
When the work happens above an occupied building, safety is not a section of the job, it is the job. Here is exactly what protects your people, your tenants and you, and what every specialist on your job already carries.
01
every specialist on your job is IRATA certified
No exceptions and no learning on your building. All rope work runs on twin lines, a working line and a separate backup, under a Level 3 supervisor.
02
RAMS before they mobilise, every time
A site specific risk assessment and method statement in your inbox before anyone clips on, not after and not on request.
03
Insured to £10m, certificates attached
Public and employer liability cover supplied with the quote, so it is in your file before you appoint the specialist.
04
Vetted before they reach you
every specialist on your job is required to hold or work to standards like CHAS, SSIP and SafeContractor. We check certification and insurance before any work starts, not after.
The price holds.
Whatever we survey it at, that is what you pay
If we have seen the building, the fixed price we quote is the number on your final invoice, barring a change you ask us for in writing. No weather extras, no nasty true up at the end, nothing the board can pick apart afterwards.
"They spotted spalling on the parapet we had not even asked them to look at, and flagged it before it turned into a Section 20. That is the difference between a contractor and someone watching your back."
Sarah WhitlockProperty Manager, Eastgate PM
"The rope access approach saved us a full scaffold and about six weeks. The paperwork was the cleanest I have had off any contractor."
James OkaforFacilities Manager, commercial landlord
"Fixed price, proper RAMS, and the final invoice matched the quote to the penny. When you are the one signing it, that is everything."

Where we work
Regional teams, one company behind them. Each city has its own page and its own recent jobs.
The four questions every careful manager asks, answered without spin.
Does Envelium do the work itself?
Yes. We verify each specialist's IRATA certification, insurance and recent work, and your work is carried out by the specialist who genuinely covers your building, under full insurance and contract.
What does using Envelium cost the building?
Nothing. Specialists pay us for verified introductions, so there is no fee on your side and no day rate of ours to inflate. Your price and your contract are agreed directly with the specialist, and your details go to that one specialist only.
If something goes wrong on site, who is responsible?
The specialist, under their own public liability insurance. That is exactly why we verify cover before any introduction, and why the certificates and RAMS arrive in writing with the quote, so the chain of responsibility is documented before anyone clips on.
Will the paperwork stand up to Section 20 and the board?
That is what it is built for. A defined scope, a fixed written quote, RAMS and insurance certificates give you a file you can put in front of leaseholders, the freeholder or a board without gaps. Our Section 20 guide walks through how facade works fit the consultation process.
We publish what we know, openly
Practical guides on what the work costs, which method suits which surface, and how to keep a building's envelope right.
Answer six quick questions, add a photo of the elevation if you have one, and a specialist who covers your area comes back with a quote, usually within one working day.
