The Point of an Evaluation Is Clarity, Not a Sale

Most people contact us because something changed and they cannot tell how serious it is. A crack appeared above a doorway. A floor started to feel uneven. A door that used to close now has to be pushed. Water arrived in a basement that had been dry for years.

The evaluation exists to answer that question honestly, in both directions. It is entirely normal for the answer to be that a crack is cosmetic, that a floor differential is within the range you would expect in a hundred-year-old house, or that the right action is to record a baseline and check again next year.

We separate the assessment from the sale deliberately, because a company that only makes money when it recommends work will find work to recommend. Being able to tell you nothing is wrong is the whole value of the exercise, and it is the basis on which we take on every Seattle foundation repair project.

What Happens on Site

Exterior walk. Foundation wall condition, visible cracking and displacement, grading in the first several feet from the house, gutter and downspout discharge, retaining structures, and how surface water moves across the lot.

Interior walk. Crack locations, orientations, and widths, recorded with dated photographs against a scale reference. Door and window operation, noting which stick and in which direction. Separation at wall and ceiling junctions. Floor covering condition, which often shows movement before anything else does.

Crawl space or basement. Where access allows: post base and pier condition, girder spans and visible deflection, joist and sill condition including probing where decay is suspected, moisture evidence, and existing anchorage and bracing.

Elevation survey. Multi-point laser manometer readings across the floor plan, producing differentials to hundredths of an inch relative to marked survey benchmark locations. This is the part that converts impressions into data.

Why the Measurements Matter

A floor that “feels off” is not information. A floor plan with recorded elevation differentials at twenty points is.

Those numbers do two things. They establish the shape of the movement, whether the floor drops toward an exterior corner, which suggests perimeter settlement, or toward the middle, which points at crawl space framing. And they create a dated baseline.

That baseline is the only way to answer the question homeowners actually care about: is this still happening? A repeat survey in twelve or twenty-four months settles it. Without a baseline, the same question can only be answered with recollection, and recollection about floor levels is unreliable in everybody.

What a Visual Assessment Cannot Establish

We are explicit about limits because an assessment presented as more complete than it is does you real harm.

A visual evaluation cannot establish subsurface conditions. We can infer likely bearing conditions from local geology, site behaviour, and the movement pattern, but knowing what is actually there at depth requires a geotechnical investigation with soil borings. We say so rather than implying the walkthrough covered it.

It also cannot see inside finished wall cavities, behind sealed crawl space access, or under slabs. Inaccessible areas are recorded as inaccessible, and the findings state what was not examined. An assessment that reports on areas nobody reached is not an assessment.

Our guide on structural versus geotechnical evaluation explains which professional answers which question.

What You Get

A plain discussion of what was observed and measured, what those findings indicate, what they do not indicate, and what was not accessible. Then a next step, which is one of four things:

Nothing. The concern is cosmetic or within normal range. No repair recommended.

Monitor. The situation is ambiguous. Record the baseline, repeat the survey after a wet season, and decide on evidence rather than on a first impression.

Repair, with a defined scope. Where movement is established and the mechanism is identified, a written proposal with quantities, depths, permit notes, and explicit exclusions.

Refer. Where the question requires engineered design, a geotechnical investigation, or a specialist trade, we say who should look at it.

When an Evaluation Is Worth Booking

Book one when you see a pattern rather than a single feature: several cracks in a consistent orientation, doors binding across part of the house, a floor that reads clearly out of level, a basement wall that appears to be bowing, or water arriving where it did not before.

Book one before listing a house, because a dated baseline answers the question a buyer’s inspector will raise. Book one before buying, because it puts numbers against a flagged concern instead of leaving you to negotiate against an unknown.

Do not book one for a single hairline crack in a basement slab or a door that sticks for two damp weeks each spring. Tell us about it in the free preliminary review and we will say so. See foundation warning signs for what genuinely warrants a look.

Emergencies Are Different

If a structure is actively moving, or a slope is visibly failing, that is not an evaluation request. Move away from the affected area and contact emergency services. A quote form is not an emergency response service. We can evaluate the property once it is safe to do so, and we would rather say that clearly than have anyone wait on a form submission.

What Drives the Cost of Evaluation?

We publish cost drivers rather than a single headline number, because a number without a scope behind it tells you nothing. Your written quote itemises quantities so you can see exactly what each line pays for.

Cost factor How it affects the quote
Preliminary project review Free. Send us what you're noticing and we will tell you what an evaluation would examine before you commit to anything.
Property size and complexity A larger floor plan means more survey points. Additions, split levels, and multiple foundation types add time.
Crawl space and basement access Restricted clearance, blocked hatches, and inaccessible perimeter sections extend the visit and limit what can be observed.
Scope of measurement A full elevation survey plus crack mapping and wall deflection measurement takes longer than a targeted look at one symptom.
Documentation depth A written findings summary for resale, insurance, or a second opinion is more involved than a verbal discussion on the day.
Travel distance Properties at the edges of our coverage in Everett, Tacoma, and Sammamish are scheduled in blocks, which affects availability more than price.

We distinguish sourced estimate ranges from completed-invoice figures, and we do not publish unsupported local averages. Permit valuations are declared values, not final customer prices.

Our approach

Why Choose Us for Evaluation

We will tell you it is nothing

The most valuable outcome of many evaluations is finding that a crack is cosmetic. That answer is available and we give it without trying to salvage a sale.

Numbers, not impressions

Elevation readings across the plan produce data you can keep and compare against later. A verbal impression cannot be re-checked in two years.

Limits stated explicitly

A visual assessment cannot establish subsurface conditions. We say what we could not see rather than implying the assessment covered everything.

Charges disclosed first

If an evaluation carries a fee, you know the amount before an appointment is booked. Nothing is discovered on arrival.

A baseline you can reuse

The survey is a dated record. A follow-up reading later establishes whether anything is actually progressing, useful for monitoring and for resale.

Referral when it is warranted

Where the question belongs with a structural or geotechnical engineer, we say so rather than stretching our scope to cover it.

Work sequence

How Our Evaluation Work Runs

Access, sequence, and restoration explained before anything starts, so you know what will happen on your property and in what order.

  1. Step 01

    Preliminary review

    You tell us what you're noticing and where the property is. We respond with what an evaluation would examine and what it cannot establish. This part is free.

  2. Step 02

    Walkthrough and observation

    Interior and exterior, crack locations and patterns, door and window operation, drainage behaviour, and the crawl space or basement where accessible.

  3. Step 03

    Measurement

    Multi-point laser manometer elevation readings across the floor plan, crack width measurement, and wall deflection where relevant, all recorded with dated photographs.

  4. Step 04

    Findings and next step

    What the findings indicate, what they do not, what a visual assessment cannot establish, and whether the honest answer is repair, monitoring, an engineer, or nothing.

Have a evaluation question about your property?

Send us the observations and photos you have. We'll tell you what an evaluation would examine and what it can't establish remotely.

Customer experience

What Customers Say About Our Evaluation Work

The evaluation was calm and thorough. They explained which cracks were cosmetic and which were load-bearing, and gave us a written scope with clear exclusions before any work.

Homeowner, Queen Anne

Queen Anne, WA

We were braced for bad news and were told the floor differential was well within normal for a house that age. No repair was recommended and none was sold to us.

Homeowner, Wallingford

Wallingford, WA

We had the survey done before listing. The buyer's inspector raised a crack, and we handed over dated readings showing it had not moved.

Frequently asked

Evaluation Questions

What actually happens during a foundation evaluation?

We walk the interior and exterior recording crack locations and patterns with dated photographs, check door and window operation, look at how surface water moves across the site, and get into the crawl space or basement wherever access allows. Then we take multi-point laser manometer elevation readings across the floor plan. Afterwards we go through what the findings indicate, what they do not, and what a visual assessment could not establish.

Is the evaluation free?

The preliminary project review is free, send us what you're noticing and we will tell you what an evaluation would look at. An on-site evaluation may carry a charge depending on the property and the scope. If it does, you are told the amount before anything is booked. Submitting an enquiry does not confirm an appointment.

Can you tell me what is wrong from a photo?

No, and we will not pretend otherwise. A photograph shows a crack without showing its context: whether the floor is out of level, whether the crack is moving, what the crawl space looks like, or how water behaves on the site. We are happy to look at photos to understand what you're describing and to tell you whether an evaluation is warranted. That is different from a diagnosis.

How long does it take?

Typically one to two hours on site for a single-family home. Larger floor plans, additions, split levels, and restricted crawl space access extend it. We would rather take the time to reach the whole perimeter than produce a quick opinion based on the accessible third of it.

What is a laser manometer survey and why does it matter?

It measures floor elevation at multiple points across the plan relative to a reference, producing differentials in hundredths of an inch. It matters for two reasons. First, it distinguishes a floor that is genuinely out of level from one that feels odd. Second, it becomes a dated baseline, repeat it in two years and you know whether anything has actually moved, which no amount of confident recollection can establish.

Will you recommend repair even if I do not need it?

No. A meaningful proportion of evaluations end with us saying the concern is cosmetic, or that the differential is normal for a house of that age and construction, or that the right action is to monitor rather than repair. That is a legitimate outcome and it is one of the reasons to have an evaluation done by someone who separates the assessment from the sale.

Do I need a structural engineer instead?

Sometimes. An evaluation establishes what is happening and whether an engineer is warranted. Where the question involves engineered design, an unusual configuration, unreinforced masonry, or slope stability, that goes to a licensed structural or geotechnical engineer and we say so. Many concerns are resolved by an evaluation and a defined scope without engineering.

Is this useful before buying or selling a house?

Yes, in both directions. For a buyer, an evaluation puts numbers against what an inspection flagged. For a seller, a dated baseline survey answers the question an inspector will raise, and documented permitted repair work is straightforward to hand over. Our guide on [buying or selling after foundation repair](/guide/buying-or-selling-after-foundation-repair/) covers what records to gather.
