Questions about the site visit
These answers cover what happens when someone arrives to book fire engineer cladding check work at your home.
- Access to individual flats
- Usually only common parts and the exterior are needed. If internal walls must be opened, the managing agent arranges flat access with residents beforehand.
- Time and notice for residents
- On a six storey block expect one full day. Residents receive written notice from the managing agent well before the date.
- Scaffolding or cherry picker costs
- If upper floors cannot be reached safely from the ground, access equipment is quoted separately and added to the total cost.
- Who commissions the work
- The freeholder or managing agent instructs the specialist. A leaseholder can enquire but needs the building owner to agree before anyone can carry out ews1 work.
- Repairing any openings made
- Small sections cut to view hidden layers are sealed and made good by the specialist before they leave the site.
- What the manager receives
- A full set of photographs, material notes and measurements goes to the block manager so the EWS1 form for flats can be completed accurately.
