Fitting an armored door, installing a roller shutter or mounting an awning secures and upgrades your home. But anyone who has been through it knows: once the installer leaves, traces of the work almost always remain. Roughly patched chases around the new frame, chipped plaster near the shutter-box fixings, drill holes in the façade render under the awning brackets, old paint shades that no longer match the brand-new joinery. These finishing touches are no longer locksmith or awning work — they are renovation work. In this article we explain what to plan for after each type of installation, and why we recommend SM Bat, a renovation company specialised in post-installation work, to our Île-de-France clients.
Why fitting an armored door leaves its mark
Reinforcing a door or installing a full armored door set is heavy work on the building fabric: removing the old frame, sealing the new steel frame, re-anchoring into the masonry. Even when done cleanly — as the teams at Iron Metal, metalwork and armored door specialists in Paris and Île-de-France, do — it calls for touch-ups: plaster repairs around the hinges, render patching along the new frame, and very often a full repaint of the entrance wall, because the original shade has aged and a local touch-up would show. This is exactly what SM Bat does: surface preparation, fillers and repainting of the entrance or landing, including in occupied homes, with floor protection and a schedule that follows the installation immediately.
New roller shutter: the box and the façade
Installing a roller shutter affects both inside and outside. Indoors, the box and the guide rails require filler and paint repairs around the window reveal. Outdoors, the fixings and the removal of any old system leave holes to fill and colour differences on the façade render. Specialist installers such as Volea Store, roller shutter installers in Île-de-France, hand over a perfectly adjusted, working unit; bringing the wall back to visual standard is a painter's and renderer's trade. SM Bat handles both sides of the problem: interior repairs around the boxes, and render patching or partial refacing on the street side, with water-repellent treatment if the façade needs it.
Awnings: fixings that go through the insulation
A quality awning is anchored into the structure of the wall, not into the render. On a façade with external insulation, that means through-bolted plates and waterproofing repairs around every fixing. Installers such as Store Xpress, awning installation specialists, use stand-off kits designed for insulated façades; the sealing and render finishing around the brackets still needs proper care, otherwise cracks or water ingress appear with the first rainy season. SM Bat specialises in external thermal insulation (polystyrene or rock wool) and its finishes — the natural partner to keep your façade watertight and uniform after the installation.
Who SM Bat are, and why we recommend them
SM Bat is a renovation company founded in 2013, based in Saint-Denis, working across Paris, Hauts-de-Seine, Yvelines, Val-d'Oise and Seine-Saint-Denis — an area that largely overlaps ours. Their core trades: interior painting, fillers and plastering, partitions and suspended ceilings, floors (screed, tiling, parquet, laminate), masonry, façade restoration and waterproofing, external insulation, and communal areas in co-owned buildings. Three things convinced us to recommend them. First, the weight they give to surface preparation — the invisible part that makes the difference two years later. Second, their experience of occupied sites: protection, dust control, organised working hours — exactly what matters when you have just had an armored door fitted and are living in the home. Third, a transparent process: site visit and itemised quote within 48 hours, fixed prices, and insurance certificates provided before work starts.
What order should the work follow?
The right sequence saves you paying twice. Start with the structural installations: door reinforcement or armored door set (with a metalworker like Iron Metal), roller shutters (with an installer like Volea Store), awning (with a fitter like Store Xpress). Have the necessary repairs noted while the installers are still on site — a photo of the chases and fixings prevents any debate later. Then bring in the renovation company: fillers and repairs first, paint next, floors last. If a full façade restoration is planned, group it with the outdoor installations in the same season: you scaffold once, and the façade is repaired around the boxes and brackets in the same operation.
What it costs, and how to avoid surprises
For localised repairs after an armored door installation, expect half a day to a day of a painter's time, fillers included. A full repaint of an entrance hall costs hundreds of euros rather than thousands. On the façade, a localised repair around a shutter box or awning plates remains modest; a full restoration is a different scale. In every case, insist on an itemised quote — surface areas, preparation, number of coats, products — and fixed prices. That is how SM Bat works, and it is how we work in locksmithing too: a free, detailed quote approved before any intervention.
Secure first, beautify next — with the right partners
Our trade at AMG Serrurerie stops where the painter's begins: we install and reinforce doors, we repair and motorise roller shutters, we fit and repair awnings — and we know how much a network of reliable partners matters for a job to be truly finished. For fine metalwork and made-to-measure pieces, Iron Metal; for a complete new roller shutter installation, Volea Store; for terrace and storefront awnings, Store Xpress; and to make it all blend into an immaculate home, SM Bat. One final tip: keep the invoices from the whole chain — installation and finishing — in the same folder. If you ever need to claim, your insurer will appreciate a complete file, and so will you.
Frequently asked questions
Should I wait between installation and finishing work? Not for interior painting: once the anchors have cured — usually 48 hours — the painter can start. For façades, simply avoid frost and heavy rain. Can't the installer do the touch-ups? A careful locksmith or awning fitter will fill holes roughly, but has neither the fillers, nor the colour matching, nor the trade skills of a painter: the touch-up will show. Two specialists beat one rushed generalist. Who coordinates the companies? You do — or the renovation company if you give them the finishing package: SM Bat offers a single point of contact who schedules around the installation date. What if I am selling the property? That is the best time for finishing work: a secured AND immaculate entrance adds value, whereas a new door in a damaged wall draws the eye to the building site rather than the equipment.
