The future remains uncertain for the 10 businesses which managed to survive a devastating fire on a Perivale industrial estate.
The savage blaze at the Wadsworth Road site, on July 4, destroyed around 25 units, leaving business owners at a total loss of their livelihoods.
The access to the estate has now be reopened but the remaining businesses, which narrowly avoided destruction, are not quite operating "as usual" yet.
Arun Ahluwalia, of Opera Opera, who make spectacle frames, said: "Businesses are mostly operating part-time.
"At the moment we have got electricity but it's all off generators.
"In the medium or long-term, we should be okay.
"Most [units] are now filthy with soot and obviously all have been affected by not having much to do over the last 10 days.
"We do not know what we are going to do because we have a big demolition site in front of us. It's like a bomb site now.
"We feel for the owners of the [businesses] that burnt down because I know most of them - they have worked so hard over the years."
Other units which escaped the fire relatively unscathed include car repair workshops and a joinery workshop.
Speaking to getwestlondon, Mr Ahluwalia added: "It was frightening to see it on Saturday night.
"We did not know where all the smoke and flames were coming from."
London Fire Brigade (LFB) revealed that around 30 people left the building before crews arrived at the incident on July 4, and a spokesman confirmed there were no reports of any injuries.
The mixed-use industrial site included a range of units including a furniture manufacturer, food wholesalers, carpet warehouse, and marshal arts suppliers.
An LFB spokesman has confirmed the cause of the fire is still under investigation.
