Hiring the wrong contractor on a commercial project? That’s a recipe for disaster.

Owners and facility managers of commercial properties throw away thousands of pounds annually by accepting the first estimate they receive in their inbox. Harsh reality, but it’s true.

  • Bad contractors blow budgets
  • Cheap quotes hide nasty surprises
  • Single bids leave you flying blind

Now when it comes to specialist skills such as plastering or plumbing for example, the bar is raised even more.

Ok here’s a list of reasons why asking for multiple quotes is the single best thing a commercial buyer can do.

  • Why Multiple Quotes Matter For Commercial Projects
  • The Real Cost Of Picking The Wrong Contractor

Why Multiple Quotes Matter For Commercial Projects

Commercial buyers all know they “should” get multiple quotes… Yet hardly anyone actually does it.

While 94% of homeowners recently polled said they would get multiple bids for large projects, only 67% do. Commercial projects are similar, as time constraints and trust in a general contractor usually prevail.

That gap costs serious money.

Here’s the truth: Two contractors can both provide identical quotes for the same plumbing job and differ by 20% to 50%. When it comes to commercial fit-outs or refurbishments, that’s not chump change. That’s the difference between turning a profit or writing the whole thing off.

For extended work such as plumbing maintenance contracts, that gap can be wider still. Experienced plumbing professionals price the whole job – pipework, fixtures, regular servicing and emergency callouts. Cheap quotes generally price out half of that and charge extra later on.

That’s why comparing several bids isn’t paranoia. It’s basic due diligence.

The Real Cost Of Picking The Wrong Contractor

Hiring the wrong plasterer or plumber is not just an expensive mistake on day one. It is an expensive mistake for years to come.

Cost overruns plague this industry. A large portion of cost overruns can be attributed to one factor…. poor contractor selection up front.

Here’s what happens when commercial buyers skip the comparison process:

  • Material substitutions – cheap plaster or low-grade copper that needs replacing years sooner
  • Hidden charges – “extras” that weren’t in the original quote

Examples of visible costs:

  • Project delays – you take on too much and your project sits still
  • Rework costs – shoddy workmanship that needs a second contractor to fix

The cheapest bid on paper is almost never the cheapest bid in reality.

Plus on a commercial project, each day of delay generates extra costs: unpaid rent, lost trading days, lost productivity. It adds up fast.

What Multiple Quotes Actually Reveal

This is where it gets interesting.

 

Obtaining three or four quotes does MUCH more than provide price comparisons. It allows you to see:

  • The going rate – so you know what’s reasonable in your local market
  • Scope differences – what one contractor includes and another excludes
  • Material quality – what brands and grades each one is proposing
  • Timeline expectations – how long the job should actually take
  • Communication style – how each one will handle the project

That’s huge.

With only one bid on the table, there is no frame of reference. Everything sounds fine all by itself. However, as soon as that second and third quote hit the desk, disparities become glaring.

One bid may come with skip hire, debris removal and a one-year workmanship warranty included. Another may exclude everything listed above.

Same price. Wildly different value.

How To Properly Compare Plastering And Plumbing Bids

Comparing quotes isn’t just about looking at the bottom line. That’s a rookie move.

Here’s a smarter way to do it…

Match The Scope

All bids should be based on the same job. Identical square metres of plastering. Identical number of fixtures. Identical materials. If one is pricing for two coats and one is pricing for one then they aren’t the same. Get them to provide quotes for the same scope before comparing them.

Check The Itemisation

Vague quotes are a warning sign. A proper commercial quote should break down:

  • Labour costs
  • Materials
  • Permits and compliance
  • Timeline and milestones
  • Payment schedule

If the bid is just one big number with no breakdown – move on.

Verify Insurance And Certifications

Especially when it comes to commercial plumbing, contractors should be covered by full public liability insurance and have the correct Gas Safe or WaterSafe registrations. Don’t just take their word for it. Get it in writing.

Read The Reviews

The internet reputation of a contractor will say it all. Read recent reviews and notice how they answer criticisms.

Red Flags To Watch Out For

After looking at dozens of commercial quotes, certain patterns emerge. Watch out for these…

  • Suspiciously low bids – usually means corners are being cut somewhere
  • Massive upfront deposits – anything over 25-33% should raise serious concerns
  • No written contract – this is non-negotiable for commercial work
  • High-pressure sales – if they’re pushing you to sign today, walk away
  • Vague timelines – “we’ll start soon” isn’t good enough on a commercial schedule

Listen to gut instincts. If it doesn’t feel right during the quoting stage it will only feel worse during actual production.

Why Plumbing Maintenance Quotes Deserve Extra Care

Plumbing maintenance is one of those areas where commercial buyers get burned the most.

Why? because maintenance contracts are long-term agreements. They aren’t a single service call – they commit you to a 12, 24, or 36 month relationship. Make a bad decision and you will be paying inflated call-out charges, waiting weeks for service, and receiving mediocre repairs for years to come.

That’s why obtaining multiple quotes for plumbing maintenance is so important. Here are some key comparisons to consider:

  • Response time guarantees
  • Callout fees vs included visits
  • Coverage of emergency work
  • Parts and labour markup

The right plumbing maintenance agreement will more than pay for itself. The wrong one will cost money little by little.

Putting It All Together

Don’t hire plasterers or plumbers for commercial work without taking the time to do it properly. The difference between quotes can save money – and the price paid for not shopping around is steep.

To quickly recap:

  • Get at least 3 detailed quotes for every commercial trade job
  • Match the scope across all bids
  • Compare value, not just price
  • Watch for red flags and trust your instincts
  • Treat plumbing maintenance contracts with extra care

Investing a few more hours in due diligence now can prevent weeks of frustration later. That’s good sense, not just good policy.
