Doors, Windows and Glass at Handover: The UAE Snagging Checklist

The developer hands you the keys, a clipboard and about forty minutes. Most buyers spend that time looking at paint and tiles. The doors, windows and glass get a glance, a slide, a nod. Eighteen months later the balcony door drags, the glass unit has gone cloudy and the warranty conversation has already closed. This is the snagging checklist we would use ourselves, written by people who fit these systems for a living in Dubai, Abu Dhabi, Sharjah and the Northern Emirates.

Why doors and glass are the expensive things to miss

Almost every snagging guide written in the UAE gives doors and windows two lines and spends the rest on paint, tiles and air conditioning. That is backwards. Paint is cheap to argue about. A scuffed skirting costs the contractor an hour. A 2.4 metre sliding door that was installed out of square costs considerably more, because fixing it properly means lifting the panel off its carriages, re-shimming the frame and resealing the threshold. That is the reason it is the category most likely to be waved away at handover with the phrase “it will settle”.

Doors and windows do not settle. They are mechanical assemblies bolted into an opening. If the opening was out of plumb on day one, the door will get worse, not better, because every cycle of a dragging panel wears the carriage a little more.

There is also a clock running. Under the UAE Civil Code, a contractor and the supervising engineer carry liability for ten years where the stability and safety of the building is concerned, and that period cannot be shortened by contract. Hidden defects can be claimed within three years of discovery. But the everyday things, the ones you can see by looking, are treated as patent defects, and a buyer who accepts handover without recording them has a much weaker position afterwards. Most developers in the UAE then layer a defects liability period on top, commonly twelve months for fit-out and mechanical items.

Before you arrive: preparing for the snagging inspection

1. Ask for the door and window schedule. Every project has one. It lists each opening, the system used, the glass make-up and the hardware. You are entitled to see it. It turns a vague complaint into a specific one.
2. Go at the hottest part of the day if you can. Between noon and four, an aluminium frame is under maximum thermal expansion. A door that binds in the heat will bind every summer. A door that only binds in January is a different problem.
3. Take four things. A phone with a torch, a 2 metre spirit level or a level app, a sheet of A4 paper and a bottle of water. That is the entire toolkit.
4. Bring a second person. One opens and closes while the other watches the frame and listens. Most door defects are heard before they are seen.
5. Allow two hours, not forty minutes. Tell the handover agent in advance. It is your property and nobody can make you sign in a hurry.

Snagging sliding and lift-and-slide doors: 11 checks

This is the system most likely to be handed over with a fault, because a sliding door is the heaviest moving object in the apartment and the least forgiving of a frame that is a few millimetres out. If you want the background on how these systems are built and specified, our page on aluminium sliding doors in Dubai goes into the frame and glass options in detail.

• Open it with one finger. A correctly hung panel on good carriages moves with light pressure. If you need a shoulder, write it down. Weight is not an excuse; the system is sized for the weight.
• Listen at the halfway point. Grinding means debris or a flat spot on a wheel. Clicking means a carriage bearing. Both are hardware faults, not wear.
• Stop it in three positions. Quarter, half and three quarters open. It should sit still in all three. A panel that creeps back means the track is not level.
• Check the gap down the interlock. Where two panels overlap, the gap should be the same at the top and the bottom. If it tapers, the panel has dropped or the frame is out of square. This is the single most common sliding door snag we see on handover.
• The paper test. Close the door on a sheet of A4 at head height, at the middle and near the floor. The resistance should feel the same at all three. If the paper pulls out freely at the bottom and grips at the top, the seals are not making even contact.
• Lift-and-slide gear. If the handle turns 180 degrees, it should drop the panel onto its seals with a firm, even feel and lift it back cleanly. A spongy or notchy handle means the gearbox or the linkage is out.
• Lock engagement with the door open. Work the handle with the door standing open. If the hooks and bolts move freely open but jam when closed, the hardware is fine and the door needs aligning. That one test saves a lot of argument.
• Flood the bottom track. Pour half your bottle of water into the outer track. It should drain away within a minute. If it pools, the drainage slots are blocked with construction debris or, worse, were sealed over by the painters.
• Look for sealant bridging the drainage. Shine the torch along the outside of the threshold. Silicone across the weep holes is a defect, not a finish, and it is the reason water appears inside after the first rain.
• Check the brush pile and gaskets. Run a finger along the interlock brush. It should stand up and feel springy. Flattened or missing sections at the ends are common and cheap to put right before you sign.
• Open it fully and look at the stack. The parked panel should clear the reveal without touching plaster. Rub marks on new paint tell you it has been catching since the day it was fitted.

Snagging folding and bifold doors: 8 checks

A bifold has more moving parts than any other door in the property, which means more things to check and more things a contractor can leave half-adjusted. If you want the maintenance side of this, we have written separately about keeping bifold doors running in the dust, and the systems themselves are covered on our folding doors in Dubai page.

• Fold the whole set, then fold it back, three times. Panels should track together without one leading or lagging. A set that needs encouragement on the third panel is not adjusted.
• Check the gaps between every pair of leaves. They should be consistent down the full height. One tapering joint usually means a hinge that was never set.
• Work the traffic door on its own. The single leaf you use daily should latch without being pulled or lifted. This is the part that gets used a thousand times a year.
• Look at the top track from below. With a torch, follow the track across the whole span. Any sag in the middle shows up as panels that run easily at the ends and stiffly in the centre.
• Check the bottom guide or floor track. On a top-hung set the bottom guides should sit in the channel without rattling. Debris here is normal on a new build and should be cleaned, not left.
• Flush bolts and shoot bolts. Every non-traffic leaf has them. Each one should drop into its socket without being forced. A bolt that needs the panel nudged is a misalignment.
• Test the closing sequence with the lock. Fully closed and locked, all leaves should sit in one plane. Run a hand across the joints from inside. A leaf standing proud means it is not pulling into the frame.
• Check hinge covers and screw caps. Missing caps are trivial to replace at handover and oddly difficult to get six months later.

Snagging windows: 9 checks

Windows get less attention than doors at handover and cause more long-term annoyance, because a window that leaks air costs you money on the air conditioning every single month. Our page on aluminium windows in the UAE covers the frame systems in more depth.

• Open every opening sash. Not a sample. Every one. Contractors fit dozens a day and the one that was forced into a tight opening is the one nobody opened again.
• Check the handle at both ends of travel. It should reach the fully locked position without resistance in the last few degrees.
• The paper test again. Close the sash on A4 at three heights. Even resistance means even compression on the gasket.
• Look at the gasket corners. Gaskets shrink back from the corners when they are stretched during fitting instead of being cut to length. A visible gap at the corner is a defect and it will whistle.
• Find the weep holes. Every aluminium window has drainage on the outer face. Check they exist and are clear. Painted-over weeps are common.
• Check the external sealant line. It should be continuous, tooled and bonded on both faces. Gaps, bubbles and shrinkage cracks are all recordable.
• Push gently on the glass from inside. There should be no movement and no creaking. A glazing bead that was not seated properly will reveal itself.
• Look for condensation inside the glass unit. Between the two panes, not on the surface. See the glass section below, because this one matters.
• Child safety restrictors. If the property is above ground level, check what is fitted and that it works. Dubai Municipality has pushed hard on window safety in towers and this is worth raising on the day rather than later.

The glass itself, and what you cannot claim later

Glass is the part of the system where buyers lose the most money by signing too quickly, because two of the three common faults are invisible unless you look for them deliberately.

Where the property has frameless glass, structural glazing or large single panes, the specification matters as much as the condition. Our aluminium and glass door page explains the common build-ups used in UAE residential work.

Shower screens, mirrors and internal glass

These rarely appear on a developer snag list and they are among the quickest things to check.

• Open and release the shower door. It should hold where you leave it and close to the magnet without being pushed. A door that swings open on its own has lost its hinge cam setting.
• Check the drip strip and bottom seal. The clear fin along the bottom edge should be present and flexible. It is the single most common cause of water on a new bathroom floor.
• Look at the silicone line where glass meets tile. It should be a neat continuous bead. Silicone is a waterproofing joint, not a fixing. If a panel feels like it is being held up by sealant, raise it.
• Check the support bar bracket. On walk-in panels, grip the bar and apply light pressure. Movement at the wall plate means the fixing is into tile alone.
• Mirrors. Look at the edges for black specks or a creeping grey line, which is early silvering failure from moisture getting behind the backing. Check the fixings are concealed and solid.

If you are replacing or upgrading any of this later, our pages on shower glass partitions and washroom mirrors cover the options and the fixing methods we use.

The three defects unique to UAE balconies

A balcony door in Dubai lives a harder life than the same door in Europe. Three things show up again and again, and all three are easier to prove on handover day than in month fourteen.

1. The threshold that was never drained

Rain in the UAE arrives rarely and then all at once. A bottom track with blocked weep holes will not show a problem for months, then will put water across your living room floor in a single afternoon. This is why the water bottle is on the tool list. It takes thirty seconds and it is the highest value check in this entire article.

2. Thermal expansion binding

Aluminium moves with temperature. A long door panel in direct afternoon sun grows measurably, and if the installer left no allowance, the door binds in July and runs perfectly in December. Checking in the middle of the day is the only way to catch this before you have lived with it for a summer.

3. Sand in the running gear

Fine sand gets into tracks during construction and nobody cleans it out properly before handover. It then works like a grinding paste on the carriage wheels. A new door that already feels gritty has sand in it, and it should be stripped and cleaned rather than lubricated. Oil holds sand and makes it worse. We go into this in more detail in our notes on balcony sliding doors and the UAE climate.

How to write a snag that actually gets fixed

A snagging list is a legal record, not a complaint. The ones that get actioned share four things, and the ones that get closed as “within tolerance” are usually missing all four.

1. Name the location the way the drawings do. Not “the big door in the lounge”. Use the room name and the opening reference from the door schedule if you have it. “Living room, opening D-04, east elevation.”
2. Describe the observation, not the diagnosis. Write “panel binds in the last 300mm of travel and the interlock gap tapers from 3mm at the head to 8mm at the cill.” Do not write “door is badly installed.” The first is a fact they must address. The second is an opinion they can dismiss.
3. Photograph with something for scale. A coin, a key, a tape. Photos without scale get argued about.
4. Give it a category and a date. Mark each item as a defect, an incomplete work or damage. Date every photograph. If it goes to a dispute later, the dates are what carry weight.

Submit the list in writing, keep your own copy, and ask for written acknowledgement of receipt. Verbal agreement with a site engineer on handover day is worth nothing in month eleven.

What the developer will argue, and what you can insist on

Where a developer accepts an item but keeps rescheduling the repair, put the request in writing and reference the end date of your defects liability period. Items raised in writing inside the period usually remain live even if the repair itself runs past it, but the written record is what makes that argument possible. For the official position on who regulates building safety and construction standards in the UAE, the government portal on building safety sets out the role of the municipalities.

After the defects liability period ends

Once the developer’s window closes, the cost moves to you, and the economics change. At that point the right question is no longer “who pays” but “repair or replace”.

• Worth repairing. Carriages and rollers, hinges, gaskets and brush seals, handles and locks, drainage clearing, alignment, single failed glass units. These are parts and labour on an otherwise sound frame.
• Worth replacing. Frames that were installed out of square, non-thermally-broken frames in direct sun, systems where the manufacturer no longer supplies the hardware, and single glazed units in a room you are trying to cool.
• The deciding factor. If the frame is true and the glass is sound, repair almost always wins on cost. If the frame is the problem, repairing hardware is paying twice.

We handle both. If you need an assessment rather than a sales visit, our window and door repair service covers diagnosis, hardware replacement and alignment across Dubai and the Northern Emirates, and the hardware replacement guide explains which parts are matched to what.
