Replacing an old iron or PVC gate with an aluminum model is often the first instinct when wanting to modernize a facade without breaking the budget. Brico Dépôt offers several references for aluminum gates, either swinging or sliding, at prices significantly lower than those of custom carpenters. The price displayed in-store is enticing, but it only tells part of the story.
Actual cost of a Brico Dépôt aluminum gate: what the in-store price doesn’t show
The label in the store corresponds to the bare gate, without installation accessories or masonry. Have you noticed that the posts are almost never included? At Brico Dépôt, an anthracite gray aluminum gate post is sold separately. You need two posts for a swinging gate, and sometimes an additional receiving post for a sliding gate.
On top of that, add chemical sealing or the creation of concrete footings if your current posts are not the right dimensions. Masonry can cost as much as the gate itself when you have to replace posts that are too narrow or misaligned. A sliding gate also requires a concrete beam poured on the ground to guide the rail.
Before comparing with a quote from an aluminum carpenter, list all the additional costs:
- The posts or caps for the pillars, sold individually and whose price varies depending on the selected store
- The replacement or creation of posts in cinder block or concrete (sand, cement, reinforcement, formwork)
- The motorization kit if you want automatic opening, which is rarely provided with the gate
- The lock, adjustable hinges, and finishing hardware
A detailed review of the Brico Dépôt aluminum gate confirms that the final “supply and installation” budget far exceeds the catalog price, especially if the existing masonry is not compatible.
Quality of aluminum and finish: what to expect concretely
The aluminum sold in DIY superstores is not a sub-product. The profiles are lacquered, generally in anthracite gray (the most requested shade), with anti-corrosion treatment. Aluminum does not rust and does not deform under the effect of humidity, unlike wood or wrought iron.
The difference with a custom aluminum gate lies elsewhere: the thickness of the profiles, the quality of the lacquer, and the number of colors available. Brico Dépôt models come in one or two standard colors. A specialized manufacturer will offer a complete RAL palette and thicker profiles, often with a longer lacquer durability guarantee.
Maintenance to consider for an aluminum gate
The technical notices recommend cleaning with soapy water two to four times a year. This simple gesture prevents the rails from getting clogged and preserves the shine of the lacquer. A poorly maintained aluminum gate dulls in a few years, not because the material degrades, but because pollution deposits attack the finish layer.
The hinges and pins deserve annual lubrication. On a swinging model, also check the adjustment of the gap between the leaves to avoid ground friction, especially if your land has shifted after a dry spell.
Installation of an aluminum gate purchased at the store: technical pitfalls
Why do so many DIYers give up halfway? Because installing a gate requires a precision that other gardening tasks do not demand. A gap of a few millimeters in the alignment of the posts can block the gate or create an unsightly gap.
Three points are consistently underestimated in competing articles:
- The laser or plumb line level check of the posts, essential before fixing the hinges
- The reservations in the masonry, which must exactly match the dimensions of the gate (check the manual before pouring the concrete, not after)
- The weight of the leaf, which makes handling by two people mandatory for a model over three meters
Brico Dépôt offers an installation service through the Needhelp platform. This service allows you to have the gate installed by a registered craftsman, simplifying the comparison between a store purchase with outsourced installation and a “supply and installation” quote from a local carpenter.
Swinging or sliding gate at Brico Dépôt: which model to choose
The choice depends on the configuration of your entrance, not on aesthetic preference. A swinging gate requires free swing space in front of or behind the posts. If your driveway slopes up right from the gate, the swinging gate will drag on the ground or need to be raised, creating a gap at the bottom.
The sliding gate moves laterally along the fence. It requires a linear clearance equal to the width of the gate, plus a margin of a few dozen centimeters. The concrete beam on the ground and the guiding rail add a masonry component that is absent on a swinging gate.
In terms of motorization, the sliding gate is easier to automate: a single motor is sufficient. The swinging gate requires two arms or two actuators, which doubles the cost of the motorization kit and slightly complicates the wiring.
Brico Dépôt against alternatives: custom carpenter or online gate
The real competitor of Brico Dépôt is not Leroy Merlin or Castorama (similar ranges and prices), but specialized online sales sites for custom aluminum gates. These manufacturers offer gates cut to your exact dimensions, delivered with all the hardware, often within a few weeks.
Custom solutions eliminate the problem of non-standard posts, which reduces the masonry cost. The gate arrives ready to install on existing posts, even if they differ from catalog dimensions.
A local carpenter adds a ten-year guarantee on the installation and a quick intervention in case of problems. Brico Dépôt guarantees the product (usually ten years on the aluminum structure), but the installation done by you or by a Needhelp craftsman falls under a different framework.
The Brico Dépôt aluminum gate remains a relevant option for a tight budget, provided you master masonry or accurately estimate the cost of subcontracting. Without this step, the final price can match that of a custom product delivered ready to install, with less flexibility on dimensions and finishes.
