Survey to close-out, in the owners' own sequence.

The brief

A third-floor apartment bought at auction with a diagonal crack across the living room wall that three previous viewers had been told was cosmetic.

What the survey found

The crack ran from the corner of an opening, which is never cosmetic. The lintel above it had settled and the plaster had followed. Everything else in the flat was sound.

What we did about it

Lintel replaced first, the wall made good in lime plaster to match the rest of the apartment rather than in gypsum. The owners then paused for eight months; we honoured the scope and it re-priced within 4%.

“We came back most of a year later and the number was the number. That does not happen.”

Nineteen weeks, with an eight-month pause in the middle.

The owners stopped after the survey and came back the following spring. The log picks up where it left off, and so did the price.

  1. Day 1

    Survey

    The crack ran diagonally from the corner of an opening, which is never cosmetic. The lintel over it had settled and the plaster had followed.

  2. Week 3

    Scope

    Lintel replacement priced first, everything else priced after it. The owners had eight months before they intended to move, so the sequence had room.

  3. Week 4

    Pause

    They paused for eight months. We honoured the scope when they came back and it re-priced within 4%.

  4. Week 11

    Structure

    New lintel set, wall made good in lime plaster to match the rest of the apartment rather than in gypsum.

  5. Week 19

    Close-out

    Delivered on date. The engineer who wrote the original note came back to sign off the repair.

They paused for eight months. The price held.
