Asbestos Survey in Guildford

Most asbestos work starts with a question that a photograph cannot answer. A survey is how that question gets settled properly, and there are two quite different surveys people mean when they use the word.

Choosing the wrong one is the single most common and most expensive mistake in this area, so it is worth being clear about which is which.

Management survey

The default. It answers the question: what asbestos is in this building, and could it be disturbed by people using the building normally?

It is non-intrusive. The surveyor inspects accessible areas, takes samples of suspect materials, and records condition and location. Ceilings do not come down and panels do not come off. Where a material is presumed rather than sampled, the report says so.

The output is a register: a list of materials, where each one is, its type, its condition and a risk assessment. That register is what a duty holder under Regulation 4 works from, and it should be a document that gets used rather than filed.

A management survey is the right survey for an ordinary building in ordinary use. It is the wrong survey if anybody is about to knock a wall down.

Refurbishment and demolition survey

The intrusive one. It answers a different question: what asbestos is in the way of the work we are about to do?

It is destructive by design. Ceilings are opened, panels are lifted, floors are gone into, ducts and risers are accessed. The aim is to find everything within the scope of the planned work, including material that is hidden and would never be found by a non-intrusive inspection.

It is the survey a demolition contractor needs, the survey a refurbishment needs before strip-out, and the survey a loft conversion or a knock-through needs. It costs more than a management survey because it involves considerably more work, and it usually leaves the building needing making good in the areas that were opened.

The failure mode here is the one worth naming. A management survey used to plan refurbishment work gives false confidence. It looked at what was visible. The work is going to disturb what was not.

How to choose between them, quickly

Nobody is doing any building work. Management survey, or often just a single sample and test on the one material you are worried about.

Work is planned that will open up the fabric. Refurbishment and demolition survey, scoped to the areas the work touches.

You have a duty under Regulation 4. Management survey, kept current, with a written management plan that comes out of it.

You are a homeowner who has found one suspect thing. A single sample is nearly always the proportionate answer, and a full survey is nearly always more than you need.

You are buying a property and want to know before you commit. Usually a management survey, though it is worth being clear with yourself about what you would do with the answer, since finding asbestos in a pre-2000 house is the expected result rather than the surprise.

What it costs

£200 to £400 for a domestic property, indicative.

The figure moves on three things. The size of the building, obviously. The number of samples taken, because each one carries a laboratory cost. And how much opening up is required, which is what makes a refurbishment and demolition survey more expensive than a management survey on the same address.

A single sample on one material costs a fraction of that, and for most household enquiries it is the right first spend. The full price context sits on the asbestos removal cost page.

What happens during one

The scope gets agreed in writing first, and that is not a formality. A survey is defined as much by what it excludes as by what it covers, and agreeing the boundaries at the start prevents an argument about them later.

On site, the surveyor works through the building systematically, recording each suspect material by location, extent, type, surface treatment and condition. Samples are taken where identification cannot be made confidently, using a method that minimises disturbance, and each sample point is made good and labelled.

Samples go to an accredited laboratory. That is the part that produces the certainty, and it is why nobody can tell you what a material is on the day with total confidence.

Then the report. It should contain a register, a plan showing where each material is, laboratory certificates, a material risk assessment for each entry, and a clear statement of what was not accessed and why.

Reading the report properly

Two sections get skipped and both matter.

Presumed materials. Where a material was not sampled, the report presumes it contains asbestos. That is the correct and conservative approach, and it means a register entry marked "presumed" is not a confirmed positive. If the presumption is going to cost you money later, it is usually cheaper to sample it now.

Exclusions and limitations. The list of what was not inspected: locked rooms, live plant, areas under stored goods, voids without access. Those are the places a subsequent surprise comes from. If the list is long, the survey is worth less than it looks.

The other thing worth doing is checking that the report is usable by the people who will need it. A register that lives in a drawer helps nobody. A contractor arriving to do maintenance should be able to look at it and know within a minute whether the thing they are about to drill is on the list.

What a survey costs you if it is wrong

Two failure modes are worth naming, because both are expensive and both are avoidable.

Scope too narrow. A survey commissioned for one building, or one floor, or one flat, that is then relied on for the whole site. This happens most often with blocks and with buildings that have been extended, because the extension was built later and was never in scope. Anyone relying on a survey should read the address and the scope on the front page rather than the conclusions on the back.

Survey too old. A register is a live document. Materials get damaged, refurbishments change what is there, and a survey from 2011 describes a building that has had fifteen years of maintenance since. There is no fixed expiry date in the regulations, because the duty is to keep the assessment current rather than to reissue it on a schedule. In practice, if nobody has looked at the register since it was written, it is out of date whatever the date on it says.

The third one is subtler. A survey that nobody can use is not much better than no survey. If the register is a PDF on a laptop belonging to somebody who left, the contractor drilling a wall next Tuesday will not be consulting it.

What to do with it afterwards

For a duty holder, the survey is the input rather than the output. What Regulation 4 asks for is an assessment, a record, a plan for managing the risk, and steps to make sure the information reaches anyone liable to disturb the material.

In practice that means four things. Keep the register somewhere findable rather than filed. Put a short procedure in place so that any contractor coming to work on the fabric is shown it before they start. Review it when anything changes or is damaged. And record what you have done, including decisions to leave material in place, because a documented decision to manage is a perfectly good answer and an undocumented one is not.

For a homeowner none of that is a legal requirement. A copy of the report kept with the house papers is still worth doing, because it answers a buyer's question in one move.

Around Guildford

Survey demand here splits fairly cleanly between two groups.

Homeowners in the pre-2000 stock, which is most of it. Burpham, Merrow, Onslow Village and Westborough for the 1930s to 1970s builds, and Park Barn, Bellfields and Stoughton for the post-war council housing. Most of those enquiries are about one material, usually a textured ceiling or a garage roof, and most are better served by a single sample than by a full survey.

Duty holders in the commercial and institutional stock. Offices and shops around the town centre, light industrial units on Slyfield Industrial Estate, and the buildings that come with the University of Surrey, the Royal Surrey County Hospital and the churches, halls and clubs across the borough. For those, Regulation 4 applies and a current survey plus a written management plan is the normal way of meeting it. That is covered further on the commercial and landlords pages.

One local practicality worth mentioning. A refurbishment and demolition survey opens up the fabric, and on a terraced or semi-detached property that means noise, dust and a surveyor working in several rooms across a day. On the tighter streets near the town centre that is worth telling a neighbour about in advance, particularly where a party wall is being opened for access.
