For most Kirkland homes, engineered hardwood is the better choice: its cross-ply core moves far less than solid wood through our wet winters and dry summers, and Wills Flooring installs both at the same $3.25 per sq ft. Solid hardwood still wins in one case: a well-conditioned house over a wood subfloor where you want a floor that can be sanded five or six times over a century. The choice is about construction and location in the house, not quality. Both are real wood on top.
Kirkland is a hard place for wood floors to sit still. Houses in Juanita and Finn Hill sit over vented crawlspaces that run damp from November to April. Lakefront homes in Houghton live in air that never really dries out. Then July arrives, the heat pump runs, and indoor humidity drops thirty points in a month. That swing is the whole engineered-versus-solid debate. Here is how each floor handles it, honestly, and how we advise people who walk into our Lynnwood showroom from the Eastside.
What the two words actually mean
Engineered
A real hardwood veneer over a plywood or HDF core
The top layer, called the wear layer, is genuine oak, hickory, maple or walnut, 2 to 6 mm thick. Under it, 5 to 11 plies run in alternating directions. The plies pull against each other, so the plank barely changes width when humidity changes. It can be nailed, glued or floated, and it can go on a concrete slab.
Solid
One piece of wood, top to bottom
Usually 3/4 in thick and 2 1/4 to 5 in wide, milled from a single board. Nothing restrains it, so it expands across its width in humid months and shrinks in dry ones. It is nailed to a wood subfloor, never floated or glued to concrete. It can be sanded down to roughly 3/32 in above the tongue, which is five or six refinishes.
Head to head for a Kirkland house
| Factor | Engineered | Solid |
|---|---|---|
| Seasonal movement | Minimal. Wide planks stay tight through winter. | Noticeable. Expect winter gaps and summer swelling, more so in wide planks. |
| Cupping risk over a damp crawlspace | Low, with a vapor retarder. | Moderate to high without strict moisture control. |
| Concrete slab or basement | Yes, glued or floated. | No, unless a plywood subfloor is built first. |
| Refinishing | Once or twice at 3 mm; three or more at 4 to 6 mm. Under 2 mm, recoat only. | Five or six full sandings over the life of the floor. |
| Plank width | Up to 9 or 10 in without stability problems. | Best at 5 in or narrower in our climate. |
| Radiant heat | Most products approved. | Generally not recommended. |
| Installation labor at Wills | $3.25 per sq ft | $3.25 per sq ft, or $2.75 unfinished plus finishing |
| Material cost | Wide range; quality tracks wear layer thickness. | Wide range; red oak strip is the value buy, wide white oak the premium. |
| Lifespan | 30 to 60 years depending on wear layer. | 80 to 100 years with periodic refinishing. |

Where each one belongs in a Kirkland home
Engineered
Choose engineered when
- The room is over a crawlspace that runs damp, or on a slab or daylight basement
- You want planks 6 in or wider
- The home has radiant heat or a heat pump that dries the air hard in summer
- You are a tech buyer flipping in 7 to 10 years and want the modern wide-plank look for resale
Solid
Choose solid when
- You are matching original 1970s to 90s oak in a Bridle Trails or Rose Hill home
- The house has good crawlspace ventilation and stable humidity year-round
- You plan to stay 20 or more years and want to refinish repeatedly
- You prefer narrower strip flooring and a site-finished, gap-free look

The moisture question, answered honestly
- Solid does not fail in Kirkland. Unmanaged solid does. Thousands of Kirkland homes have 30-year-old solid oak that looks great. Those homes have a dry crawlspace, a vapor retarder under the floor and heat that runs through winter.
- The crawlspace decides more than the weather. We check crawlspace moisture and the subfloor reading at every estimate. A subfloor above 12 percent moisture is a problem for either floor, and a bigger one for solid.
- Summer is the dangerous season for solid. People worry about the rain, but the winter swelling is gentle. It is the fast summer dry-down with the heat pump running that opens gaps and can split boards.
- Lakefront is a special case. Houghton and Juanita Beach homes live at high ambient humidity year-round. That stable dampness is actually fine for either floor, as long as acclimation is done at that humidity, not in our warehouse.
- Acclimation is not optional. Solid needs 5 to 7 days in the house at living conditions. Engineered needs 48 to 72 hours. Skipping this is the number one cause of the cupping complaints we get called to look at.
Three myths we hear on Eastside estimates
"Engineered is fake wood"
The surface you walk on is exactly the same oak or hickory as a solid board. A 4 mm wear layer is thicker than what most solid floors have left after two sandings.
"Solid adds more resale value"
Kirkland buyers and their inspectors look at species, width, finish and condition. Almost none can tell engineered from solid without pulling a register, and appraisers do not price them differently.
"Engineered can't be refinished"
Thin, builder-grade engineered cannot. A 3 mm or thicker wear layer sands the same way solid does. We do it regularly. Buy the wear layer, not the brand.
The trap to avoid: The cheapest engineered floors have a 1 to 1.5 mm veneer. They look fine on day one and cannot survive a single sanding, so a deep scratch or a pet accident means replacement. For a Kirkland home you plan to keep, we recommend a 3 mm minimum and 4 mm if the budget allows. We show the cut edge of every sample at the estimate so you can see what you are buying.
How to decide in one visit
- Start with the subfloor, not the showroom. Slab, crawlspace or basement rules out solid before you fall in love with a sample.
- Pick a plank width. Anything over 5 in points to engineered in our climate.
- Decide how long you are staying. Under 15 years, engineered at 3 mm is plenty. Over 20 and you love oak, solid earns its keep.
- Compare wear layer, not price per box. Ask for the number in millimeters and get it on the quote.
- Get labor and material on separate lines. Our labor is the same for both, published at the price list. If your project is over a slab, read our hardwood installation guidance first.
