Update your cleaning scope after a home extension

Review the whole change, not just the new panes

A completed extension may add windows or doors, but it can also alter the approach to glass that was already part of a cleaning arrangement. An upstairs window may now sit above a roof. A side route may have moved. An old opening may have been removed or become internal. Update the description of the property so the agreed service reflects those changes rather than simply adding a pane count to the previous arrangement.

Begin with a short comparison: what is new, what has gone and what is reached differently? You do not need a full set of construction drawings for an ordinary enquiry. Focus on the changes that affect the surfaces or access. If a drawing or photograph explains one awkward feature, use it as supporting information rather than assuming the cleaner can infer the whole new scope from it.

Use a change list with three columns

These are possible categories, not assumptions about your project. Include only the items that apply. An honest “uncertain” is useful where you do not know whether a product has a coating or how an altered roofline should be described. The cleaner can ask the relevant next question rather than work from a confident but inaccurate description.

Separate finishing work from ongoing service

The first clean after building work can raise residue questions that are different from future routine cleaning. Mention paint spots, adhesive or other unusual deposits before agreeing that first scope. Do not assume an ongoing external arrangement includes specialist removal of construction residue or repair of damaged glazing. If a defect is being assessed by the installer, keep that issue visible.

Once the new surfaces and access are understood, the recurring service can be considered separately. Use domestic window cleaning for the ordinary external arrangement. The regular external service has a minimum commitment of four cleans; this does not automatically apply to a separate one-off finishing task or an additional interior appointment.

Identify the extras by their own names

Roof glazing should be raised through the skylight and roof-window information. If the new room contains glass that needs cleaning from inside, use internal window cleaning. If new fascia, soffit or gutter sections are wanted, name those separately rather than assuming they enter the window scope because they arrived with the same building project.

Pass on available product guidance for new coatings, films or unusual materials. The installer handover is a useful place to look. There is no need to obtain a difficult label from the roof or try an unfamiliar opening mechanism simply to make the cleaning enquiry more complete.

Explain one hypothetical change clearly

Imagine a household whose existing rear bedroom window now sits above a kitchen extension, with new glazed doors below. Their update should mention both the new doors and the changed position beneath the older window. Simply saying “we have added doors” leaves out the access change that may matter most. If the new roof also contains a rooflight, that becomes its own surface and product question.

Check the final service description against the change list and retain it for future appointments. Remove obsolete room or window descriptions so a later appointment does not refer to a pane that has become internal or no longer exists. If building work is still continuing, state which details are confirmed and which may change. The aim is a current, accurate cleaning arrangement for the completed property, with new extras and unusual first-clean conditions explained before they become assumptions.
