What we actually do, in plain English.

We've been finishing metal in Dagenham since 2006.

Stainless steel, bronze, brass. Mirror, satin, brushed, patinated.

We work on buildings, on sculpture, and on restoration projects across the UK.

If you've ever wondered whether HGMP could help with something you've got coming up, this should answer it.

And if it doesn't, we're always happy to talk it through.

The London Festival of Architecture started on the 1st of June.

This year's theme is Belonging.

We've been thinking about what that means for us, finishing metal in a workshop in Dagenham.

A building isn't only its shape.

It's the handrail you grab when you're tired.

The lift surround you stand next to every morning.

The cladding by the front door that catches the light on the way home.

Those are the surfaces people actually live with.

They decide whether a place feels like yours or not.

That's the part we make.

If you've got an LFA-season project in progress, or a spec coming together for later this year, we'd love to talk.

Appointing the wrong finishing contractor on a serious project is an expensive mistake. Not because the work obviously fails, it usually doesn't, but because a surface that's almost right is still wrong, and fixing it costs more than getting it right the first time.

These are the six questions worth asking before you sign anything. Not to catch anyone out, but because the answers will tell you quickly whether the contractor in front of you has actually done this kind of work before.

Can you show me examples at a similar scale to this project?
A good finish on a small piece and a good finish on a 4-metre installation are different skills. Ask to see both if the project warrants it.

How do you handle join treatment on large-format work?
The joins between panels are where finishing either holds or falls apart. A contractor who hasn't thought about this in detail hasn't done enough large-scale work.

Will this be workshop finishing or site finishing, and what's the difference in outcome?
Both are valid. But they produce different results, and you should understand which applies to your project and why.

What information do you need from us before you can quote accurately?
A vague quote is a risk. A contractor who asks good questions before quoting is a contractor who understands the job.
Who will actually be doing the work?
Not who runs the company. Who is on the tools for your specific project. On specialist work, this matters.

What does your sign-off process look like — how do you know when a finish is right?
There is no instrument that definitively measures a mirror finish. The answer to this question tells you whether the contractor is working to a standard or just working.

We're happy to answer all of these for any project you're considering bringing to us.

The Peninsula Hotel opened in London in 2023 as one of the most considered hotel interiors in the city. Every material decision in that building was deliberate. The metalwork was not an exception.
Richard Hudson's Harmony Sculpture sits in a space where the lighting is precise and the audience is attentive. A surface inconsistency that might pass unnoticed in a public square is visible here from across the room.

Our work on this piece focused on what it always comes down to at this level: consistency. Not just a high finish grade, but that grade held evenly across the full scale of the sculpture, under every angle of light the space creates. The result is a piece that holds its presence in a room designed to have none.

If you're working on a commission for a hospitality, cultural, or residential project where the finish is part of what makes the piece work, we'd like to hear about it.

A mirror finish looks the same on day one whether it's going into a controlled gallery or an open courtyard. By month six, they're different surfaces.
This isn't a failure of the finish. It's physics, and it's entirely predictable if you know what to plan for.
The infographic below maps the first twelve months of a mirror-finish stainless steel surface exposed to a typical UK outdoor environment. What's happening at each stage, what becomes visible, and what the implications are for specification and maintenance planning.
The three things most people don't account for:
UV doesn't damage the steel, but it affects any protective coating applied over it. Once that coating degrades, the rate of surface change accelerates.
Pollution in urban environments attacks the chromium oxide layer that gives stainless its corrosion resistance. The finish dulls faster in a city than in a rural setting, sometimes significantly.
Thermal cycling, the expansion and contraction of metal through temperature changes, affects large-format panels differently to smaller pieces. Joins and edges are the first places it shows.
None of this means a mirror finish is wrong for an outdoor installation. It means the specification needs to account for where the piece is going, not just what it looks like in the workshop.
We're happy to advise on finish specification for outdoor commissions before anything is agreed. The earlier that conversation happens, the better the outcome.

We get asked this more than you'd think. Usually by someone who's done a fabrication course, or an art school graduate who's become obsessed with surface and material, or occasionally a parent whose teenager has decided they want to work with metal.

Here's what we actually tell them.

The technical side is learnable faster than most people expect. Abrasive sequence, compound selection, machine technique, six months of proper work and you can produce a competent finish. That's not the hard part.

The hard part is learning to read a surface. To stand in front of a piece of polished metal and know, not measure, know – whether it's right. To understand what a finish will look like in the space it's going into, not just in the workshop. To recognise the three things that are about to go wrong on a job before they go wrong.

That takes years. There's no shortcut to it.

The other thing we tell them: this is a small industry. The people who commission serious work, artists, architects, developers, commission it from people they trust. Trust gets built through the work, through doing jobs where the standard mattered and meeting it. It doesn't get built through a portfolio website.

If you want to do this, find a good workshop and spend time in it. Not shadowing. Working.

We're always willing to talk to people who are serious about this trade. If that's you, get in touch.

We started in 2006. At the time, the brief was straightforward: specialist polishing for artists and fabricators who needed a level of finish most companies couldn't reliably produce.

Nearly twenty years later, the brief is the same. The knowledge behind it isn't.
What changes over that kind of time isn't the technique. The technique is learnable in months. What changes is judgment, the ability to stand in front of a surface and know, before any measurement, whether it's right. To read a brief and anticipate the three problems that aren't written in it. To understand what a client means when they say a surface doesn't feel right, even when it passes every technical check.

That judgment doesn't come from a course. It comes from doing the work, making mistakes on jobs that mattered, and being trusted with pieces where there was no margin for error.
We still work on every job the same way we always have. Small team. Direct involvement. No hand-off to a junior once the tricky part is done.

If you're working on something where the finish matters, not just as a detail, but as the thing the whole piece depends on, that's exactly the kind of work we're here for.

Every few months we get an enquiry that starts with the same line: "The contractor told us it was maintenance-free."

It never is. There is no such thing as a maintenance-free metal finish in a real environment. What varies is how much maintenance a well-specified finish actually needs, and whether the people who commissioned it understood that before they signed off.

Here's what usually happens. A developer or commissioner asks about longevity. A contractor, keen to close the job, says the words "maintenance-free" or "self-cleaning" or "no ongoing care required." The client hears what they want to hear. The project completes. Three years later, someone calls us.

By that point, the surface has usually gone one of two ways. Either it's dulled gradually and nobody noticed until it became embarrassing, or it's been cleaned incorrectly, the wrong product, the wrong cloth, used regularly, and the damage is cumulative and largely irreversible without a full restoration.

The honest version of the conversation is this: a correctly specified metal finish in the right environment needs very little maintenance. An inspection once a year, a professional clean every two or three years, a protective coating reapplied when it starts to degrade. That's a modest cost against the value of the installation.

What it is not, under any circumstances, is nothing.

If you're commissioning metalwork and someone tells you it won't need maintenance, ask them to put that in writing. The conversation that follows will tell you everything you need to know.

There is a category of work where the finish isn't part of the brief. It is the brief.

Anish Kapoor's Cloud Column works because of what the surface does. The distortion, the pulled reflection, the way the viewer finds themselves caught in the metal, none of that happens without a polish that is consistent and without variance across every degree of curvature.

You cannot check this with a gauge. You stand in front of the surface at different angles, in different light, and you feel whether it's right. That judgment is what the work depends on.
We were trusted with this piece. It remains one of the projects we're most proud of.

If you're working on a commission where the surface is the sculpture, where the finish isn't a detail but the reason the piece exists, we'd like to hear about it.

Most artists come to us knowing exactly what they want the surface to feel like. Fewer know which finish will actually get them there, and why the same grade can look completely different depending on the form, the scale, and where the piece is going.

We offer five finishes. From orbital sand, a hand-worked, non-directional texture, through to superior mirror, the standard required for plating and for work where complete surface clarity is the point.

The guide below covers all five. What each one does to light, what it demands from the piece, and where it tends to go wrong.

A few things worth knowing before you brief anyone:
The finish that looks right on a 30cm sample often reads differently on a finished sculpture. Scale changes how light moves across a surface, and what feels considered at small size can feel flat at large.

Superior mirror on a concave form concentrates light and amplifies every inconsistency in the polish. It is the most demanding finish to achieve correctly, and the most powerful when it is.

Satin and orbital sand finishes are more forgiving over time, but satin has a grain direction. How that sits relative to the viewer matters more than most people realise until they see the piece installed.

If you're developing new work and you're not sure which finish suits what you're trying to achieve, that's a conversation worth having before the fabrication is done, not after.

We work with artists at the specification stage as well as the finishing stage. Get in touch.
