Why Is the Builder's Repair Estimate So Much Lower Than Mine?

You know your home or community has defects. Now someone has to put a dollar figure on fixing them, and the builder's number is often far from yours.

Picture an HOA board that receives a repair estimate from its own consultant. Then the builder's expert responds with a figure that is a fraction of it. Which number is correct?

In most construction defect cases, the repair estimate is the backbone of the entire claim. Whoever wins the cost-of-repair argument usually controls the value of the case.

We have resolved 1,000+ cases and recovered $500M+ for homeowners and HOAs, and repair cost battles are at the center of that work. Below, we explain who the cost-of-repair expert is, how an estimate is built, why the builder's number is lower, what a scope-of-repair dispute looks like, and who pays for experts.

How Does Colorado Law Define Damages in a Construction Defect Case?

Colorado construction defect claims are governed by the Construction Defect Action Reform Act (CDARA), C.R.S. 13-20-801 et seq.

Under C.R.S. 13-20-802.5, "actual damages" are generally the lesser of three amounts: the fair market value of the property without the defect, the replacement cost, or the reasonable cost to repair. Residential owners may also recover relocation costs and other direct economic costs related to loss of use. Interest, costs, and attorney fees may also be recoverable where a contract or law allows.

In most cases, the "reasonable cost to repair" is the number that drives the claim, which is why cost-of-repair experts matter so much.

Before a lawsuit moves forward, CDARA's notice of claim process under C.R.S. 13-20-803.5 gives the builder a chance to inspect and offer to repair. That first repair offer often previews the scope fight to come.

Who Is the Cost-of-Repair Expert in a Construction Defect Case?

A cost of repair expert witness in Colorado is typically a construction estimator, general contractor, or construction consultant who prices the work needed to fix the defects correctly. This expert usually works as part of a team:

• Engineers and building envelope or structural experts identify the defects and their causes.
• Those experts design the repair, which defines the scope of repair.
• The repair cost estimator prices that scope.
• In some cases, a construction damages expert or appraiser addresses diminished property value or loss of use.

Credibility matters. A strong cost of repair expert has real-world experience building and repairing similar projects and uses current local Colorado pricing. This expert can also explain the numbers clearly to a judge, jury, or arbitrator.

Colorado courts require experts to be formally disclosed with their opinions and the basis for them under Colorado Rule of Civil Procedure 26(a)(2). Every number has to be supported.

How Is a Construction Defect Repair Estimate Built?

A credible estimate comes together step by step:

• Investigation and testing: visual inspections, moisture readings, and often intrusive testing (opening walls, roofs, or decks) to see what is really happening behind finished surfaces.
• Repair design: engineers specify the correct fix, not just a cosmetic patch.
• Quantities: measuring how many windows, square feet of stucco, linear feet of flashing, and so on.
• Unit pricing: applying current Colorado labor and material costs.
• Soft and indirect costs: permits, engineering and design fees, construction management, general conditions, contractor overhead and profit, and a reasonable contingency.
• Code compliance: work required to bring repairs up to current building code when the work triggers it.
• Owner-related costs: relocation, storage, and loss of use where applicable.

Many of the most significant costs in a real repair are not the materials themselves. They are the access, demolition, protection, and rebuilding work required to do the repair correctly.

Homeowners and HOA boards should document everything and keep any prior repair invoices. Avoid making permanent repairs that destroy evidence before your experts have inspected.

Why Does the Builder's Expert Always Come In Lower?

It is common for the builder's number to be dramatically lower. That does not mean your estimate is inflated. The gap usually comes from a few predictable choices:

• Narrower scope: treating the defect as isolated instead of systemic.
• Spot repairs instead of full replacement: sealant or patches where removal and reinstallation is required.
• Missing indirect costs: leaving out overhead, profit, permits, design, contingency, or general conditions.
• Unrealistic pricing: assuming the builder's own discounted labor or subcontractor rates rather than market rates a homeowner would actually pay.
• "Betterment" arguments: claiming the proper repair upgrades the home beyond what was promised.

The builder's expert is often pricing the cheapest fix that might work. Our experts price the repair that will actually last.

CDARA's "reasonable cost to repair" standard is where these arguments collide. The reasonableness of each line item is what gets tested in depositions and at trial.

What Does a Scope-of-Repair Fight Look Like?

A scope-of-repair dispute is an argument over what work is actually necessary, before anyone argues about price. Common examples include:

• Windows: the builder proposes re-caulking, while the homeowner's expert shows the flashing was installed wrong and the windows must be removed and reflashed.
• Stucco or siding: the builder proposes patching cracks, while testing shows water intrusion behind the cladding that requires removal and replacement across entire elevations.
• Decks or balconies: the builder proposes a surface coating, while the real fix requires rebuilding the waterproofing and framing beneath.

These fights are won through testing data, photographs from intrusive testing, manufacturer installation requirements, and building code requirements. They are also won by experts who can connect the evidence to the repair.

Whoever proves the scope usually wins the number. The price follows the scope.

If the builder makes a repair offer during the CDARA notice process, do not accept it until an independent expert reviews whether the proposed scope actually fixes the problem.

Who Pays for Construction Defect Experts?

Many homeowners and HOAs worry that expert costs will make a claim unaffordable. That concern is understandable.

Expert costs in construction defect cases can be significant because of testing, analysis, reports, and testimony. In many of our cases, we work on a contingency basis and typically advance expert costs, so clients are not paying out of pocket as the case moves forward.

Costs and attorney fees may also be recoverable where a contract, HOA governing documents, or applicable law allows. This is consistent with the actual damages definition in C.R.S. 13-20-802.5 discussed above.

The right team, including a qualified construction damages expert in Colorado, is an investment in the value of your claim, not just an expense.

How Nelson Law Approaches Repair Cost Battles

We have resolved 1,000+ cases and recovered $500M+ for homeowners and HOAs. We take on fewer cases by design, so each one gets the experts, testing, and trial preparation it needs.

Our trial-ready reputation matters here. Builders know our repair numbers will be defended in front of a jury.

What Should You Do Next?

• Do not accept the builder's repair estimate or repair offer at face value.
• Preserve evidence and avoid permanent repairs before an expert inspection.
• Gather documents: purchase or construction contracts, warranties, HOA governing documents, photos, and prior repair records.
• Be mindful of deadlines. Colorado construction defect claims have strict time limits under C.R.S. 13-80-104, so get advice early.

Have you received a repair offer, a low estimate, or a builder response that does not match what you are seeing in your home? If so, it is time to talk to a construction defect attorney.
