Window Screen and Screen Door Repair Bookkeeping: Costing Every Stop, Tracking Every Roll, and Surviving the Winter Trough

The first 70-degree Saturday of spring does something strange to your phone if you run a screen repair business: it rings forty times before lunch. Torn winter screens, bent patio doors, a landlord with twelve units that all need rescreening by May 1. By October, the same phone goes quiet for weeks. If your books treat those two seasons the same way, the spring rush will feel like prosperity and winter will feel like an ambush — even in a year when you did everything right.

Screen repair looks like a simple trade from the outside: mesh, spline, frames, and a roller tool. But the bookkeeping has three quirks that separate it from general handyman work. First, your materials come in grades whose costs differ by an order of magnitude, and picking the wrong one for a job quietly erases your margin. Second, you are a mobile-route business, so drive time and mileage are a real cost of every ticket, not overhead you can wave away. Third, demand is brutally seasonal, so cash-flow planning matters more than it does for a year-round shop. Get these three right and a modest route business throws off excellent margins. Get them wrong and you will be busy all spring and broke by February.

Why Screen Repair Books Differ From a Handyman's​

A general handyman bills mostly labor plus marked-up parts, with demand spread across the year. A screen shop has a different shape:

• Jobs are small and numerous. A rescreen of an existing window frame might sell for well under a hundred dollars, while a full replacement screen or custom sliding door runs into the hundreds. Volume and route density decide profitability more than any single ticket.
• Materials are the margin lever. Standard fiberglass mesh costs a fraction of specialty fabrics like solar screen, pet-resistant mesh, or extra-fine no-see-um weave. Two jobs that take the same twenty minutes can carry wildly different material costs.
• The calendar is the boss. Spring and early summer bring the flood; fall tapers; winter is maintenance, storm damage, and commercial work — or nothing at all. Your books need to move spring surplus into winter survival deliberately, not accidentally.

Set up your chart of accounts to reflect this reality from day one: separate revenue lines for rescreens, new-frame builds, screen door work, and commercial or landlord contracts; separate material cost lines by mesh grade; and a vehicle cost line you reconcile monthly. That structure is what makes every section below possible.

Price the Work Around Three Job Types​

Most screen shops live on three kinds of tickets. Price and track each differently.

1. Rescreening existing frames​

The customer brings (or you pick up) an intact frame; you replace mesh and spline. This is your highest-margin, fastest-turn work — often twenty minutes or less per window once you have a rhythm. National pricing data for 2026 puts full professional screen replacement in a wide band, roughly $75 to over $500 per screen depending on size, material, and whether the frame is reused or rebuilt — with rescreens of existing frames at the low end and custom work at the high end. Simple patch kits retail for a few dollars, which tells you something important: customers who call you instead of buying a patch are paying for convenience and fit, so price for it.

Book rescreens as their own revenue line. Track average revenue per rescreen monthly. If it drifts downward while material costs hold steady, you are discounting under competitive pressure without noticing.

2. New frames and rebuilds​

Bent, corroded, or missing frames mean cutting aluminum stock, mitering corners, fitting hardware, and screening — a shop job, not a driveway job. It commands a higher price and carries higher material and labor cost. Keep rebuild revenue separate from rescreen revenue so you can see which one actually pays your rent. Many owners discover rebuilds feel premium but earn less per hour once cutting, fitting, and callbacks are counted honestly.

3. Screen doors and custom work​

Sliding patio doors, swinging screen doors, retractable units, and oversized or arched openings are the top of your ticket range — a custom sliding door can exceed $200 installed, with hardware and specialty mesh pushing higher. These jobs deserve written quotes with line items for mesh grade, frame stock, hardware, and labor, because a misjudged custom job can wipe out a week of rescreen profit. File the quote with the job record so warranty callbacks can be checked against what was actually promised.

Know Your Mesh Grades — They Are Your COGS​

Mesh is not mesh. The industry's own specifications — the Screen Manufacturers Association publishes separate standards for standard window and door screens, retractable units, metal protection screens, warning labels, and attachment test procedures — exist precisely because grades differ in strength, weave, and application. Your books should mirror that reality. At minimum, track four cost tiers:

• Standard fiberglass (typically 18x16 weave). The workhorse. A 30-inch by 100-foot roll retails around $60 and covers roughly eight windows, putting raw mesh cost at a few dollars per window. Crease-free, easy to install, and the default for most rescreens.
• Aluminum mesh. Stronger and more tear-resistant than fiberglass, but it dents and creases, which means more installer care and occasional rework. Costs more per roll; reserve it for jobs that need durability and price accordingly.
• Specialty fabrics: solar, pet-resistant, and extra-fine (20x20) insect mesh. These can cost several times standard fiberglass per roll — a bulk roll of extra-fine weave runs into the hundreds of dollars. They command premium pricing, but only if you quote them as upgrades instead of absorbing the difference.
• Consumables and hardware: spline, frame stock, corners, rollers, handles, latches, and hinges. Individually cheap, collectively significant. A forgotten $8 latch on thirty jobs a month is real money.

Practical system: assign each job a mesh-grade code on the work order, and reconcile mesh purchases against jobs completed each month. If you bought enough pet-resistant mesh for forty jobs and billed thirty, the gap is waste, unbilled upgrades, or installer generosity — all fixable once visible. This one reconciliation catches more margin leakage than any other habit in a screen shop.

Cost the Route, Not Just the Job​

Here is the mistake that sinks mobile screen businesses: quoting the twenty minutes at the customer's house and forgetting the twenty-five minutes each way. Fuel, vehicle wear, and windshield time are direct costs of a route business. Treat them that way.

• Set a trip charge or minimum. A single-window rescreen across town can lose money without a minimum ticket or trip fee. Publish it, apply it consistently, and track how often it is waived — waivers are discounts and should show up as such.
• Log mileage per stop, not per day. The IRS standard mileage rate for 2026 started at 72.5 cents per mile and rose to 76 cents per mile for the second half of the year. At those rates, a 30-mile round trip costs over $20 in deductible vehicle cost before your time. A daily total hides which stops were profitable; per-stop logging reveals them. A simple mileage app plus a work-order number per stop is enough.
• Price route density into quotes. Three houses on one street should beat three houses across the county. Offer landlords and property managers a per-unit route rate for same-day, same-location work — it fills your schedule efficiently and gives them a reason to hand you the whole building instead of shopping each unit.
• Reconcile the vehicle line monthly. Whether you use the standard mileage rate or actual expenses, compare vehicle costs against route revenue every month. If vehicle cost per stop creeps up, your service area has sprawled, your scheduling has loosened, or fuel has moved — all fixable, none visible without the number.

For a deeper treatment of mileage records and vehicle deductions, the documentation habits in /docs/ carry over directly: contemporaneous logs, business purpose noted, totals reconciled to the return.

Build a Cash-Flow Plan Around the Seasons​

Seasonality is the defining financial fact of this trade. Spring brings the rush as homeowners open windows and discover winter damage. Summer stays steady. Fall tapers. Winter is thin — storm damage, the occasional commercial retrofit, and pre-booked spring work if you sell it. A year-round handyman can run on monthly autopilot; you cannot. Plan in four moves:

1. Bank the spring surplus on purpose​

Decide in advance what share of peak-season profit becomes a winter reserve — many seasonal operators target enough to cover three to four months of fixed costs (insurance, storage or shop rent, loan payments, phone and software). Move it to a separate account when the money arrives, not when winter starts. Money that sits in the operating account in June will be spent by August; that is not a character flaw, it is just how operating accounts work.

2. Sell winter revenue in summer​

The cheapest winter dollar is one a customer commits to in July. Offer fall screen-removal and storage, winter storm-damage inspections, and discounted pre-booked spring rescreens with a deposit. Deposits are liabilities, not revenue — record them as customer deposits and recognize the income when the work is done. Done right, a deposit program converts the spring rush from a scheduling crisis into an orderly backlog.

3. Chase counter-seasonal work deliberately​

Property managers turn units year-round. Commercial buildings, schools, and hospitality properties schedule maintenance in off-peak months. Storm seasons create sudden demand spikes — operators report surges in mobile repair requests after severe weather damages screens and frames. Track which of these actually produced revenue last winter, double down on the winners, and stop marketing the ones that only produced quotes.

4. Budget fixed costs against the trough, not the peak​

When deciding whether you can afford a shop upgrade, a second van, or a full-time hire, test the payment against February revenue, not May revenue. If the math only works in peak months, the purchase is a peak-month luxury wearing a year-round obligation's clothing. Seasonal businesses die from fixed costs set during optimism, not from slow winters alone.

Tax and Recordkeeping Essentials​

Small-route trades share a set of tax traps. The screen shop version:

• Supplies versus inventory. Mesh rolls, spline, and frame stock that become part of the customer's screen are inventory-like materials; track purchases and ending stock so cost of goods sold reflects what you actually used, not what you bought. Tools — rollers, saws, spline tools — are equipment; capitalize and depreciate what qualifies rather than expensing it into oblivion.
• Mileage records win audits. The per-stop log recommended above doubles as your substantiation. Date, destination, business purpose, miles — contemporaneous, every time.
• Classify helpers correctly. Spring rush tempts every owner to pay extra hands in cash as day labor. If a helper works your schedule, on your route, with your tools, that relationship looks like employment no matter what you call it. Misclassification penalties dwarf whatever the payroll taxes would have cost. Use proper payroll or legitimate contractor arrangements, and keep the records.
• Warranty callbacks are data. A rescreen that fails in three months costs a free revisit plus reputation. Log callbacks by mesh grade, installer, and supplier batch. Patterns — one supplier's spline shrinking, one installer's corners popping — show up fast in a log and never show up in memory.

Mistakes That Quietly Erase Margin​

Watch for these five, in roughly the order they strike new owners:

1. Quoting standard mesh and installing premium. The customer mentions a dog, the installer grabs pet-resistant mesh, nobody updates the ticket. The mesh-grade code on every work order exists to kill this one.
2. Free pickups and deliveries. Driving across town twice for a $40 rescreen turns a profitable job into charity. Trip charges, route batching, or customer drop-off — pick at least one.
3. No-show windows with no deposit. Custom doors and full-house jobs should carry deposits. Your future self, staring at a cut-to-size arched screen nobody claimed, will be grateful.
4. Winter optimism spending. Signing a year of new fixed costs in June because June felt endless. Run every commitment past February first.
5. Blended books. One revenue line and one materials line for the whole business. You cannot fix what you cannot see — split rescreens, rebuilds, doors, and commercial work, and split mesh grades in materials.
