Should we install drapery before or after the HVAC switchover?

After the house is at occupied humidity if you can. Installing silk or linen in 70% RH and then running heat will drop moisture and change length. Leave a documented ease or schedule a revisit after two weeks of heat.

Why did the wood floor show gaps in October?

Summer install in a humid house, then first heat cycle. That is moisture, not a ‘bad floor.’ Ask what EMC the installer targeted and whether the HVAC was running during acclimation.

Can we speed up for a holiday party?

You can. You then own the callback. Put a humidity range and a revisit in the letter of agreement if the install happens in this two-week window.

Does art on the wall change anything?

Yes. Dry air and new lighting are collection events. Spec HVAC and art scheduling as separate workstreams — see replacement-value vs furniture plan.

Fall Textiles vs the First Heat Cycle: Why Rushed September Installs Wrinkle, Fade, and Gap

September 3, 2026 · Guide · 1 min read

Designers who specify fall textiles in August and install in the first week of September are installing into a humidity cliff. Furnaces turn on. Indoor RH drops. Drapery hems lift. Solid wood shows gaps that were invisible at punch. Clients call it workmanship. It is often sequence vs weather.

Put occupied humidity in the install notes. Compare designers in cities or near you. For original works on the same project, keep insurance scheduling off the FF&E spreadsheet: replacement value vs furniture plan.

Specify this week

Target indoor RH range for install and for two weeks after heat is on.
Which textiles get a planned revisit (silk, linen, wool rugs on new pads).
Wood acclimation days with HVAC in heating mode, not ‘windows open, it’s nice out.’
Who owns the callback if a hem is 3/4" off after the first cold week.

A holiday-party deadline is a real constraint. It is not a reason to skip moisture language. Designers who will write the revisit into the fee are cheaper than designers who argue in October. Browse city indexes.
