Sagging cabinet shelves in Lynn, MA are almost always about the material and the gap it has to cross, rather than anything you did. Custom Cabinets Lynn fixes most of yours at $120 to $600. Rebuilding a drawer box whose corners have opened, or whose bottom has dropped, costs you $180 to $450 in dovetailed hardwood. We build it to your opening rather than to a catalog size. The number that settles the argument is 15 lb per square foot, held for seven days. That is what the cabinet industry standard, ANSI/KCMA A161.1, asks of your shelf and its fixings. Every price here sits on our cabinet price guide with its source.
A shelf that bows under a stack of your dinner plates was not overloaded. It was underbuilt, and there is a test that tells you so.
The standard loads a shelf like yours at 15 lb per square foot and holds it there for seven days. Then it looks for sag, for joints coming apart and for the fixings pulling out. A square foot of your stacked plates weighs a little more than that. Either way, half-inch particleboard crossing 30 inches will not pass.
Your drawers fail differently. Either your corners come apart, where the staples have given up, or the bottom drops out of its groove. Both of those are about how the box was made, not about what you put in it. Which one you have decides whether you are buying a repair, a new box or a new runner.
What has actually failed
A shelf that has bowed in the middle
Two things decide this: how far your shelf has to reach, and how thick the board is. Half-inch particleboard over 30 inches sags under ordinary kitchen weight, and the same reach in 3/4-inch plywood does not. We replace them in plywood at $120 to $600, depending on how many you have. Where you want to keep the shelf you own, we glue a strip of hardwood along the front edge, which turns a flat board into a beam and stops the bow.
Shelf pins pulling out of the cabinet side
Pin holes in your particleboard sides wear oval under load. Once one side drops, the shelf tips and the remaining pins take the whole weight at an angle. The tell is a shelf sitting crooked rather than one that has bowed evenly down the middle. We plug the holes with hardwood and drill them again rather than filling them. Filler in a pin hole gives you a repair with about a month in it.
A drawer box that has opened at the corners
A thin box with stapled corners gives up under the sideways shove of your drawer being slammed. Once one corner opens, the box goes out of square and your drawer front sits crooked. We rebuild it in dovetailed hardwood at $180 to $450, which means corners cut to interlock rather than stapled. Our door shop in Lawrence runs those in maple, white oak or walnut on a 1 to 2 week lead. We build to your opening rather than a stock size, because a 1946 kitchen rarely offers one.
The drawer bottom that has dropped out of its groove
Drawer bottoms are the thinnest panel in any cabinet and they sit in a shallow groove. Weight in the middle bows the panel until it leaves that groove at the back of your drawer. Where the box is otherwise sound this is the cheap end, at $120 to $600, because you need a new bottom rather than a new box. Your heaviest drawer is nearly always the one beside the range, so that is where we look first.
The runner, where the box was never the problem
A drawer of yours that drags, tips forward when open or will not close the last inch is usually a runner rather than a box. A Blum runner that hides under the drawer is rated for a drawer full of pots, and a heavier side-mount runner goes further again. That matters because your widest pan drawer gets past the rating faster than anything else in the kitchen. Your runner hardware is $7 to $15 a pair, and $60 to $180 a drawer fitted.
How we find out which one it is
-
We measure the reach and the thickness before anything else
We measure how far your shelf has to reach and how thick the board is. Those two numbers predict a sag better than any story about what you kept on it. They tell us whether you need a new shelf, an edge strip or an extra support.
-
We pull your drawer right out and look at the joint
We take the drawer completely out of the cabinet, because a box fault and a runner fault look identical while the drawer is still in place. You can do this one yourself before we arrive, and the answer changes the quote by a couple of hundred dollars.
-
We check what the load is actually sitting on
We look at your cabinet sides, the pin holes and the supports rather than only at the shelf, because a sound shelf on a failing side is a different repair. In a particleboard box, the sides are also where a pull-out or a heavy appliance garage has done damage nobody has noticed.
-
We rebuild in material that meets the number
We replace shelves in 3/4-inch plywood and drawer boxes in dovetailed hardwood. We specify both against the 15 lb per square foot the standard asks for, not against whatever was there before. Your new shelf is cut to the actual opening, which in an old kitchen is rarely the size the old one was.
-
We refit your runners and set the front
We reset or replace your runners, then adjust the drawer front so the gaps match its neighbors. A new box in your old run shows straight away if the front sits proud. Blum parts come through North Reading, so a same-week fix is normal for you rather than lucky.
The numbers that decide whether a repair holds
Why people here call us about a sagging shelf
Nobody wants to be told a shelf sagged because they put too much on it. Usually your shelf was too thin for the gap it had to cross. Most Lynn kitchens went in during the seventies or later, on half-inch particleboard shelves. We swap those for 3/4-inch plywood at $120 to $600, or glue a hardwood strip along the front edge of the one you own. A rebuilt drawer box in dovetailed hardwood is $180 to $450, cut to your opening.
15 lb per square foot, held for seven days
The cabinet industry standard, ANSI/KCMA A161.1, loads a shelf at 15 lb per square foot and leaves it there for a week. Then it checks for sag, for joints opening and for the fixings letting go. That turns a vague complaint about cheap cabinets into a question you can settle. The same standard opens and shuts a door 25,000 times, about twenty years of daily use. We write the number your new shelf is built to on the quote.
The reach and the thickness decide a shelf, not the brand
Half-inch particleboard crossing 30 inches sags under ordinary kitchen weight, and 3/4-inch plywood over the same gap does not. Gluing a hardwood strip along the front edge stiffens a shelf more than doubling its thickness would, because depth at the edge is what resists bending. That is why your fix can cost $120 rather than a whole new cabinet.
Nothing here is filed, and some of it is still regulated
Your plumbing, gas, wiring, structure and exits all stay where they are, so the state treats this as an ordinary repair and nothing is filed or inspected. In a pre-1978 kitchen, cutting or sanding painted cabinet interiors still falls under the state lead-safe rules past 6 square feet of disturbed paint, 454 CMR 22.00. That is why a shelf job in a 1946 house sometimes carries a line for sealing the room.

| What the job is | Typical range | Unit |
|---|---|---|
| Simple cabinet repairA loose door, a broken shelf, a cabinet floor that has given way, a face frame joint that has opened. The visit and the fix together. | $120 – $600 | per repair |
| Hinge repair or replacementUsually done in pairs, because when one hinge cup has pulled out of the door the other is already loosening. Cheapest repair on the table. | $30 – $80 | per door, parts and labor |
| Drawer runner hardware, materials onlySide-mount runners at the bottom of that. An undermount soft-close set costs several times this and is a different line. | $7 – $15 | per pair |
| Drawer runner replacement, installedPulling the drawer, taking off the old runner, drilling and setting the new one, then adjusting the front so the reveal matches its neighbors. | $60 – $180 | per drawer |
| Soft-close hinge retrofit across a kitchenEvery door in a normal kitchen changed over at once. Worth doing as a set rather than one at a time, because the doors need re-adjusting either way. | $600 – $1,600 | per kitchen |
| Rehanging and re-squaring a run of doors after settlementWhere nothing is broken and nothing lines up. Common in older houses where the floor has moved under the base cabinets and taken every reveal with it. | $220 – $700 | per run |
| Rebuilding a drawer box in dovetailed hardwoodWhere the old box has split at the corners or the bottom has dropped out. Made to the opening rather than to a standard size, so the front and the reveals stay as they were. | $180 – $450 | per drawer |
| Replacing a water-damaged sink base or dishwasher end panelA particleboard base that has swollen under a slow leak does not dry back. It gets replaced, and the neighboring boxes get checked before anything new goes in. | $400 – $1,400 | per box |

Questions we get asked
Why are my kitchen cabinet shelves sagging?
The reach and the thickness. Half-inch particleboard crossing 30 inches sags under ordinary kitchen weight. The industry standard asks a shelf and its fixings to hold 15 lb per square foot for seven days, and yours was never built to it.
How much does it cost to fix a sagging cabinet shelf?
$120 to $600 for most repairs. That covers a new 3/4-inch plywood shelf, repaired pin holes, or a hardwood strip glued to the front of the shelf you already have. The strip is often your cheapest real fix, because depth at the front edge is what resists bending.
Can a broken drawer box be repaired or does it need replacing?
A dropped bottom in a sound box is a repair at $120 to $600. Corners that have opened mean the joint has failed. We rebuild yours in dovetailed hardwood at $180 to $450, which is the fix that holds, and we build to your opening rather than a stock size.
How do I tell a drawer box problem from a runner problem?
Pull your drawer completely out. A box that goes out of square, has an open corner or a loose bottom is a box problem. A drawer that drags, tips forward or will not close the last inch is a runner, and we fit those at $60 to $180 a drawer.
How much weight should a kitchen drawer hold?
A Blum runner that hides under the drawer is rated for a drawer full of pots, about 75 lb. Your pan or plate drawer reaches that quickly, which is why the widest drawer beside a range is usually the first to fail.
Who repairs cabinet shelves and drawers near me in Lynn?
Custom Cabinets Lynn repairs shelves, pin holes, drawer boxes and runners across Lynn and the North Shore at $120 to $600 on most jobs. We measure the reach and the thickness first, because those two numbers predict a sag better than anything else.
Shelves and drawer boxes are the cheapest things in a kitchen to put right and the most annoying to live with. Most of what we fix here costs less than $600. We would rather rebuild five of yours than talk you into replacing a run that is otherwise sound.
If your drawers are dragging rather than breaking, hinge and drawer slide replacement is the cheaper job at $30 to $80 apiece. Where a base has gone soft underneath, water damaged cabinet repair is the one to read, and everything we handle lists the rest.
