Uneven Flooring | CBH Reviews

We are homeowners, not structural engineers or flooring contractors. This page documents flooring issues observed in our home.

The Issue

Observation	Location	Verification Method
Visible slope	Every room in the house	4-ft level shows unlevel surface
Marble rolls toward center	Every room in the house	A marble placed on floor rolls consistently toward center of house
Spongy or bouncy spots	Kids’ playroom, kitchen, and other areas	Floor compresses noticeably when stepped on
Rooms and furniture vibrate	Kitchen, upstairs, master closet	Furniture shakes and doors rattle when someone walks by
Lifted ridges, hard lumps, exposed tack strip nails	Every room in the house	Visible and tactile
Creaking floors	Upstairs hallway, stairs, kids’ playroom, kitchen	Audible squeaking and clicking

Observed: The marble rolls toward the center of the house on both floors (upstairs and downstairs).

Timeline

April 14, 2025: Filed warranty claim with 2-10 HBW documenting flooring issues throughout the house, along with window, door, and other defects.
April 21, 2025: 2-10 HBW listed open warranty items including squeaky upstairs floors, noticeable dips in first-floor subfloor, and other flooring defects. Some unrelated items (tight windows, molding gaps) were marked completed.
April 27, 2025: Filmed video walkthrough documenting flooring issues and window/door concerns.
April 28, 2025: Submitted video walkthrough and floor level measurements to 2-10 HBW.
April 29, 2025: Submitted video of kitchen and dining area squeaking and clicking LVP to 2-10 HBW. See Additional Flooring Issues.
May 1, 2025: 2-10 HBW acknowledged receipt of documentation and forwarded to CBH.
May 21, 2025: CBH proposed a repair visit for May 29 at 9 AM to address remaining items.
May 21, 2025: We requested scope details for each repair item and noted a structural engineering evaluation was pending, with a report expected by May 23.
May 22, 2025: CBH relayed that flooring repair would take two days starting at 8 AM, with flooring crew arriving at 9 AM on May 29 and 30.
May 31, 2025: Fresh air intake item marked completed by CBH. Flooring items remained open. See Fresh Air Intake Disconnection.
June 4, 2025: We received the structural engineering report and informed 2-10 HBW we needed time to review it with the engineering firm.
June 10, 2025: Submitted structural engineering report to 2-10 HBW. The report documented four deficiencies: missing bottom-chord bracing on kitchen floor trusses, excessive floor deflection in master closet exceeding L/180 and L/240 limits, sub-floor sheathing delamination at fastener lines, and joist spacing/sub-floor thickness combination at maximum capacity.
July 2, 2025: CBH responded that joists at 24 inches on center with 3/4-inch OSB decking meet 2018 IRC requirements. Proposed a framer site visit for July 16 at 3 PM.
July 16, 2025: CBH framer site visit. The team arrived without the engineering report or necessary personnel. The visit was inconclusive.
July 28, 2025: We followed up with 2-10 HBW noting four weeks had passed since the inconclusive July 16 visit with no update on the repair plan or next steps.
August 12, 2025: 2-10 HBW redirected us to the new CBH warranty portal for future submissions.
August 22, 2025: CBH service coordinator acknowledged the claim was under review alongside the engineering report.
September 11, 2025: We followed up noting nearly three weeks since the August 22 update and over two months since the July 16 site visit.
September 16, 2025: CBH reviewed the engineering report findings item by item. Missing bottom-chord bracing: none observed, bracing to be added if joists run a continuous span. Excessive floor deflection: classified as within spec, no repair required. Sub-floor delamination and squeaks: repeatable squeaks approved for repair. System at maximum capacity: classified as code compliant, no repair required.
September 16, 2025: We noted that raised ridges between subfloor panels exceeding the 2-10 HBW tolerance of 1/4 inch in 32 inches had not been addressed in CBH’s review.
September 17, 2025: CBH agreed that areas exceeding the measurement tolerance would be reviewed and repaired. Proposed sending the framer to measure and mark affected areas.
September 30, 2025: Framer visited to measure and mark areas exceeding tolerance.
October 15, 2025: We followed up noting over two weeks since the September 30 framer visit with no update.
October 24, 2025: We followed up again requesting updates on all outstanding issues, including non-flooring items.
October 27, 2025: CBH offered repair dates of November 12 or 13 at 9 AM, with carpet retuck the following morning. Scope included carpet removal in master bedroom, master closet, loft, and bedroom 2. One hallway area qualified for repair. Framer to install bracing in crawlspace around kitchen island.
October 28, 2025: We confirmed availability for November 13 and 14.
October 31, 2025: CBH stated master bathroom flooring was upgraded after closing and could not be repaired under warranty. We clarified the issue was the subfloor, not the surface flooring.
November 11, 2025: CBH obtained approval for the master bathroom repair despite the flooring upgrade. Lumber delivery scheduled for Wednesday, repair for Thursday.
November 13, 2025: Framing sub-contractor performed repair work in crawl space. See Flooring Damage from Repair Work for what followed.
November 19, 2025: Sent detailed follow-up to CBH recapping the November 14 site visit. CBH acknowledged the sub-contractor used a nail gun instead of screws, the work was performed incorrectly, and the entire downstairs flooring would need replacement. Ridges and squeaks had also migrated to new areas upstairs.
December 4, 2025: CBH proposed the framer return to correct the crawlspace work, then replace the kitchen flooring, and reassess upstairs during the same visit. Offered December 11 at 9 AM.
December 8, 2025: We informed CBH we were not available for scheduling until after the new year.
January 14, 2026: We informed CBH we were arranging a third-party evaluation of all work completed to date.
February 26, 2026: Submitted second structural engineering report to CBH. Requested that the recommended work be completed as specified in the report. Window and carpet issues first reported on April 14, 2025, remain unresolved.

CBH Response

September 16, 2025: CBH reviewed the structural engineering report and classified excessive floor deflection as within spec (no repair required). Repeatable subfloor delamination squeaks were approved for repair. System at maximum capacity was classified as code compliant (no repair required).
September 17, 2025: CBH agreed that areas exceeding the 2-10 HBW tolerance of 1/4 inch in 32 inches would be reviewed and repaired.
October 31, 2025: CBH initially stated the master bathroom could not be repaired because the flooring was upgraded after closing. After we clarified the issue was the subfloor, CBH obtained approval for the repair.

December 4, 2025: CBH proposed a corrective plan including the framer returning to fix the crawlspace work, replacing the kitchen flooring, and reassessing the upstairs.
