Sealed Gap under the door The lineup
Garage door seals, tile leveling kits, an attic cover and neoprene foam — tap any product to check the current price.
A replacement bottom seal that pairs a U-shaped skirt with a round O-tube to close the gap between the garage door and the floor. The 5/16 in T-ends slide into the existing retainer track with no screws or nails, and the flexible rubber stays workable from -40°F to 140°F. Cut it to your door width and keep rain, drafts, dust and leaves outside.

This threshold strip bonds to the garage floor and gives the closed door a 0.6 in raised line to seal against. Adhesive and sealant come in the box, so the job is clean, peel, stick and seal, with no drilling. A full-length yellow stripe and non-slip ridges keep it visible underfoot and under tires, and the rubber is rated from -40°F to 180°F.

A pack of 500 leveling spacer clips for tile jobs with 1/8 in joints. Each clip sits under the tile edges and holds neighbouring tiles at the same height while the mortar sets, then snaps off before grouting. As a guide, 100 clips cover about 25 sq ft of 12x12 in tile or about 65 sq ft of 24x24 in tile; wedges and plier are sold separately.
Check Price
Everything needed to start leveling: 300 spacer clips for 1/8 in joints, 100 reusable wedges and a push plier that seats each wedge with one squeeze. It works on floor and wall tile, keeping edges flush until the mortar cures so the finished surface is free of lippage. On a standard layout, plan on about four clips and four wedges per tile.
Check Price
The same U+O rubber bottom seal, offered here with aluminum T tracks of 40 in each for doors whose old retainer is worn, bent or missing. The 5/16 in T-ends slide straight into the track, and the rubber is rated from -40°F to 140°F. Choose it when you want to renew the whole bottom edge of the door, not just the rubber.
Check Price
A high-volume kit for big floors: 3,500 spacer clips for 1/8 in joints plus a 16 oz rubber mallet with a fiber-core handle. The clips suit tile from 1/8 in (3 mm) to 1/2 in (12 mm) thick and hold each piece in position while the bed sets. Wedges and plier are not included, so pair it with a wedge set if your method needs them.

A full 20 ft run of U-shaped bottom seal for wide double garage doors, 3 3/4 in across with 5/16 in T-ends for standard retainer tracks. Seven rounded ribs along the underside press into the floor to close small dips and gaps. The seal is rated from -40°F to 140°F and cuts to length for a clean fit.
Check Price
A box-shaped cover that closes over the attic ladder opening, the spot where the stairs leave a hole in your ceiling insulation. It measures 25 x 54 x 11 in, is built from double-layer aluminum foil insulation, and opens with a zipper so you can still climb through. Use it to cut drafts, dust and excess attic heat at the hatch.
Check Price
A roll of closed-cell neoprene foam that you cut to whatever shape the job needs. The adhesive backing sticks it straight onto drawers, panels or housings for liners, gaskets, sound deadening in vehicles or vibration pads under speakers. The sheet is 12 x 59 in and 1/4 in thick, with black and non-adhesive versions also offered.

See the Full RangeFix the gaps
Most of the hassle around a house starts with a gap somewhere. Here is how DGSL closes them.
The problem
Leaves, rain and a strip of daylight get in under the garage door.
Our fix
A U+O bottom seal slides into the door's 5/16 in track and squashes flat against the floor when the door closes.
The problem
The slab dips, so the door never meets the floor evenly.
Our fix
A 0.6 in threshold strip bonds to the floor with the included adhesive and gives the door a raised line to close against.
The problem
New tile edges end up at different heights.
Our fix
Leveling clips and wedges hold neighbouring tiles flush until the mortar sets, then the clip tops snap off.
The problem
Warm and cold air leak through the attic ladder opening.
Our fix
A zippered foil cover closes over the stair opening on the attic side and still lets you climb through.
Who we are
DGSL makes practical gear for the places where a house lets the outside in. Our range started at the bottom of the garage door, where a worn or missing seal leaves a strip of daylight, a puddle after every storm and a drift of leaves on the floor, and it has grown into the other gaps homeowners deal with: the attic ladder opening that leaks air into the hallway, the tile edge that sits a fraction higher than its neighbour, the panel or drawer that needs a soft, cut-to-shape liner.
Everything we sell is meant to be fitted by the person who owns the problem. Our bottom seals slide into a standard 5/16 in retainer track and are cut to the width of your door. The threshold strip goes down on a clean floor with the adhesive and sealant that come in the box. Tile leveling clips, wedges and pliers turn lippage control into a repeatable routine for a first bathroom floor or a large kitchen job. The attic cover zips open for access, and the neoprene foam roll cuts to any outline you draw on it.
We describe each product by the numbers that decide whether it fits — T-end size, width and length for seals, joint size and piece count for clips, outer dimensions for the attic cover, thickness for the foam — so you can measure once and order with confidence. Browse the range below, compare the specs with your door, floor or hatch, and pick the piece that closes your gap.
Buyer guide
Start with the problem in front of you — each card points to the products that solve it.
Your door has a retainer track and the rubber at the bottom is torn, flattened or gone. A U+O bottom seal slides in and closes the gap.
When the old retainer is past saving, renew the whole bottom edge with a seal that comes with 40 in aluminum T tracks.
If the slab dips or slopes toward the door, glue a raised threshold to the floor so the door has a line to close against.
Get clips, reusable wedges and a plier in one box, then add clip packs as the job grows.
A bulk pack of clips with a rubber mallet covers big rooms without running back to the store mid-job.
Close the ladder opening with a zippered foil cover, or cut neoprene foam into liners, gaskets and sound pads.
Our purpose
Our mission at DGSL is to make the small, unglamorous fixes around a home easy to get right the first time. A garage door that lets in water, a tile floor with a lip you can feel through your socks, an attic hatch that turns the hallway cold in winter — none of these are big projects, but they are the ones that stay on the list for years because the right part is hard to find or hard to fit.
So we keep our products simple to choose and simple to install. Seals come in clear lengths and a standard 5/16 in T-end, threshold strips ship with their own adhesive and sealant, and tile clips come in three joint sizes and pack sizes from a single room to a whole floor. We list the dimensions that matter up front, because an honest spec sheet does more for a buyer than any slogan.
When you choose DGSL, the goal is a job you finish in an afternoon and stop thinking about: no daylight under the door, no lippage in the tile, no draft at the attic ladder. That is the standard we hold every product in the range to.
“Close the gap. Do it once.”
Every DGSL product exists to seal, level or insulate one specific gap — and to do it well enough that you do not have to come back to it next season. Measure first, choose the size that fits, and fit it once.

Why us
Six reasons homeowners and tilers reach for DGSL.
We list the measurements that decide fit on every product. For door seals that means the 5/16 in T-end, the width and the length. For tile clips it is the joint size and piece count, and for the attic cover the full 25 x 54 x 11 in footprint. You can hold a tape measure to your door, floor or hatch before you order. That saves a return trip and a half-finished job.
Our products are designed for the owner to install. The bottom seal slides into its track with no screws or nails. The threshold strip goes down with the adhesive and sealant in the box. Tile clips and wedges turn leveling into a simple, repeatable step. Most jobs fit into a free afternoon.
Garage seals come in lengths from 10 to 20 ft and in black, grey and white. Tile clips come in 1/8, 1/16 and 1/32 in joints and in packs from 500 to several thousand pieces. You buy the amount the project needs, not the amount a single box happens to hold. Leftovers stay useful for the next job.
Our bottom seals are rated from -40°F to 140°F, and the threshold strip from -40°F to 180°F. That covers frozen winter driveways and summer sun on a south-facing door. The rubber stays flexible enough to squash against the floor every time the door closes. The yellow stripe on the threshold keeps it visible underfoot.
We try to put everything for the job in one box. The starter tile kit pairs clips with reusable wedges and a plier, and the bulk pack adds a rubber mallet. The threshold strip ships with its own sealant. The track version of the bottom seal replaces the old retainer as well as the rubber.
Garage door, bathroom floor, attic hatch, toolbox drawer — the same practical approach runs through every DGSL product. Once one fix has worked, you know what to expect from the next one. Our range grows around the gaps homeowners actually deal with. And every piece is described plainly so you can choose it in minutes.
Lengths, joint sizes and dimensions are listed for every product in the official store.

The difference
Plenty of seals and tile tools look alike in a product photo; the difference shows up when you try to fit them. Our garage door bottom seals combine a U-shaped skirt with a round O-tube, so the rubber has something to squash against an uneven floor instead of folding flat, and the 5/16 in T-ends slide into a standard retainer without screws or nails. For doors whose track is past saving, the same seal comes with 40 in aluminum T tracks.
We also try to put everything needed for the job in one box. The threshold strip includes its adhesive and sealant, the starter tile kit pairs clips with reusable wedges and a plier, and the bulk clip pack comes with a rubber mallet. You are not left halfway through a project hunting for the one part the listing forgot to mention.
Finally, DGSL sells on specifications, not superlatives. Lengths, widths, joint sizes, piece counts, temperature ratings and dimensions are listed for every product, so you can compare them with your own measurements before you order. That is the most useful promise a brand in this category can make.

What people notice
Common themes in feedback on the range, summarised in our own words.
A recurring theme with the bottom seals is how completely they close the gap — once fitted, the line of light along the floor disappears, and so do the leaves and critters that used to slip under it.
Buyers often mention that the seals slide into the track without a fight, especially with a little soapy water as a lubricant, and that the attic cover goes up in a short session with a staple gun.
People who fit the attic cover frequently describe a hallway or stair area that feels less drafty and closer to the temperature of the rest of the house.
Tilers and first-time DIYers alike point out how the clips and wedges keep edges flush while the mortar sets, which makes a level floor far easier to achieve.
Value for money comes up often, from tile kits that cover a full room to seals that renew a whole door edge in one go.
Owners of the neoprene foam like how easily it cuts to shape and how the adhesive backing holds while still allowing a quick reposition.
Good to know
DGSL focuses on a narrow job: closing the gaps around a home and helping tile go down flat. Every product is described by the numbers that decide whether it fits — T-end size, width and length for door seals, joint size and piece count for tile clips, outer dimensions for the attic cover, thickness for the foam. That makes it easy to check a product against your door, floor or hatch before you order, which is the best test of any brand in this category.
We would rather show you the details than make broad claims. Our bottom seals combine a U-shaped skirt with a round O-tube and slide into a standard 5/16 in track without screws or nails. The threshold seal ships with its own adhesive and sealant. Tile clips come in 1/8, 1/16 and 1/32 in joint sizes and in packs from a few hundred to several thousand pieces, so you buy the amount your project needs. Compare those specs with any alternative and pick what suits your job.
Start with the problem. Daylight, water or leaves under the garage door call for a bottom seal if your door has a retainer track, or a threshold strip if the floor itself is uneven. For new tile, choose the joint size first (1/8, 1/16 or 1/32 in), then a kit with a plier and wedges if you are starting from scratch, or a bulk clip pack if you already own the tools. Drafts at the attic ladder call for the 25 x 54 x 11 in attic cover, and odd-shaped gaskets, liners or sound pads are a job for the neoprene foam roll.
Orders are placed through the official DGSL brand store, so returns and any coverage follow that store's policy for your order. The current terms are shown on each product page before you check out, which is the most reliable place to confirm them.
We do not make environmental or certification claims we cannot back up. What we can say is practical: the wedges in our tile leveling kits are reusable from one job to the next, our seals and foam are cut to length so you only use what the gap needs, and a well-sealed garage door or attic hatch lets less outside air into the house.
A bottom seal attaches to the door itself: its T-ends slide into the retainer track along the bottom edge, and the rubber squashes against the floor when the door closes. A threshold seal is glued to the floor under the door and gives the door a raised line to close against. If your door has a track and the floor is reasonably flat, a bottom seal is usually enough. If the slab dips, slopes or lets water run in, add a threshold strip — many owners use both.
Look at the bottom edge of the door. Our bottom seals are made for retainer tracks that take a 5/16 in T-end; measure the slot or the bead on your old seal to confirm. Then measure the full width of the door and choose a length of 10, 12, 16 or 20 ft, since the seal is cut to fit. If the old track is bent or missing, the version with 40 in aluminum T tracks replaces it as well.
A new seal is often thicker than the worn one it replaces, so the door touches the floor a little earlier than before and the opener may read that as an obstacle. Check your opener's manual and adjust the close travel or force limit so the door can finish its stroke. Once it closes fully, the seal should sit evenly along the floor with no daylight showing.
Match the clip to the grout joint you plan: 1/8 in for a standard joint, 1/16 or 1/32 in for tight joints with rectified tile. As a rough guide, 100 clips cover about 25 sq ft of 12x12 in tile, about 40 sq ft of 12x24 in tile and about 65 sq ft of 24x24 in tile. Larger tiles need fewer clips per square foot, and it is worth adding a margin for cuts and edges.
