Old House Bedroom Storm Windows

Vendor Comparison · Premium Tier

Vendor	Product	Cost / window	Lead time	Install difficulty	Notes
Allied WindowPick Cincinnati OH · 800.445.5411	Window Saver custom low-profile aluminum, integrated screen, factory color match (bronze or putty for the Old House)	$450 to 650	3 to 4 wk	Beginner-friendly with a helper. Mounts to existing wood casing with screws. No structural change to the opening.	Period-correct enough that the Park Service uses them. Triple-track means summer venting and a screen in one frame, which the wood-storm options don't give you.
SpencerWorks Lincoln NE · 402.499.7848	True wood storm with concealed slider. Mortise and tenon construction, 100-year design life.	$400 to 600	4 to 8 wk	Hangs on hooks like a traditional wood storm. Easy install, but seasonal swap means storage space and a step-ladder dance twice a year.	Most authentic option. Best for a front-elevation visible window. Bedrooms are not your most prominent facade.
Adams Architectural Millwork Dubuque IA · adamsarch.com	Custom clear-pine wood storm windows, made to match historic profile.	$550 to 700	6 to 10 wk	Same as SpencerWorks. Hung wood storms with seasonal swap.	Overlaps with SpencerWorks on function. Worth a quote if you want a second wood-storm bid.

Why Allied wins for these openings: bedrooms need year-round function. Summer venting was the primary urgency. Triple-track with integrated screen means one frame that does both jobs. A wood storm requires taking it down in spring, storing it, installing screens, then reversing in fall. Three windows times two swaps a year is real labor. Allied solves that without sacrificing the historic read.

Sequencing · Fully after Dennis

Phase 0Pre-start

Tell Dennis the storm swap is decoupled Caleb

When you renew Dennis's quote, confirm: storm replacement is a separate future project, not part of his scope. He does his standard paint job per the original quote (remove existing storm, paint casing, reinstall the existing storm). Ask him to handle the existing storms gently on reinstall so they come off cleanly later: stainless screws he can back out, moderate caulk bead rather than heavy, no fasteners driven deeper than necessary.

Phase 1Dennis's job · Days 1–N

Dennis does his thing Dennis

Standard paint scope per his original quote. He removes the existing storms, preps casings (lead-safe), paints the wall and the storms, reinstalls the existing storms. No bedroom storm coordination, no scope adder, no special handling beyond gentle reinstall.

Phase 2After Dennis demobilizes

Wait for paint to cure, then measure with the existing storms in place Caleb

Give Dennis's paint at least 30 days to cure before disturbing it. Measure each opening with the existing storm still installed by reading dimensions off the wood casing inside the storm flange. Steel tape, not fabric. Width at top, middle, bottom; height at left, center, right; square check. Photograph each measurement.

Phase 3Same week

Email Allied for quote, place deposit Caleb

Send all three sets of dimensions plus Old House style notes (factory color matched to Dennis's final exterior color, screen integrated, no muntin overlay). Allied typically requires 50 percent deposit on custom orders. Lead time clock starts now, typically 3 to 4 weeks.

Phase 4Week 3 to 4

Storms arrive, inspect on delivery Allied

Open the cartons within 48 hours of delivery to validate dimensions, color match, and shipping damage. Allied honors warranty claims faster when reported promptly. Dry-fit each storm against its labeled opening (without removing the existing storm yet) to confirm sizing.

Phase 5Weekend after delivery · Morning

Remove the existing storms with appropriate PPE Caleb

Even though Dennis's fresh paint encapsulates the old lead, drilling and unscrewing into that paint creates dust and chip-out that carries some lead exposure risk. Wear a P100 respirator, protective eyewear, and disposable gloves. Lay a plastic drop cloth under each window before starting. Back out screws gently using the same drive Dennis used. If a screw strips or the storm sticks to the caulk, score the perimeter with a utility knife rather than yanking. Bag the old storms for scrap metal disposal. HEPA-vacuum the area before installing the new unit.

Phase 5Same weekend · Afternoon

Install all three Allied storms over one weekend Caleb

All three windows are reachable from a step ladder. Plan roughly two hours per window for a first install, faster on the second and third once you've found the rhythm. Work the same protocol on each one.

Verify the right storm goes in the right opening. Allied ships each unit labeled to your measurement spec. Match label to opening and lay the storm against the casing dry. Confirm the perimeter has roughly 1/16 to 1/8 inch gap on all four sides for caulk. Too tight or too loose, stop and call Allied before continuing.
Prep the casing. Wipe the wood clean of dust, sand any rough spots smooth with 220 grit, confirm the surface is dry. Dennis's prep should mean this takes 5 minutes per window.
Mark mounting holes. Hold the storm in position, square it with a level, and mark each pre-drilled flange hole onto the casing with a pencil through the hole. Allied units typically have 4 to 6 holes per side.
Pre-drill pilot holes. Use a 5/64 inch bit for #6 stainless screws. Drill straight in, depth roughly 3/4 inch. Skipping pre-drilling on old-growth wood casing splits the wood.
Lay a continuous bead of polyurethane caulk on the back of the storm flange. Run the bead around top and both sides, but break the bead at the bottom edge so any condensation can drain out. Use a quality exterior caulk like OSI Quad or Loctite PL Premium, not cheap silicone.
Press the storm into the opening and start the corner screws first. Square it with a level as you go. Drive each stainless screw snug, not crushing. Overdriving warps the aluminum flange and breaks the caulk seal.
Work outward from corners. After the four corner screws are set, fill in the middle of each side. Re-check level after every two or three screws.
Run a finish bead of caulk around the exterior perimeter. Tool the bead smooth with a wet finger or a caulk tool. Do not caulk over the weep holes at the bottom. They are usually two small slots in the bottom rail. Confirm they are clear.
Test sash and screen operation. Slide the upper sash, lower sash, and screen panel through their full range. They should move smoothly with no binding. If anything sticks, loosen the nearest screw a quarter turn and re-test.
Clean up and photograph the finished install. Wipe excess caulk off the glass and casing immediately. Take a photo of each completed window for the project log and for Dennis to reference when he comes back for touch-up.
Repeat for windows 2 and 3. Stage all materials at each window before starting so you are not making trips back to the garage mid-install.

Phase 6Same weekend or following

Touch up the casing yourself Caleb

Pick up a small can of Dennis's exact paint (color and product) before he demobilizes so you have it on hand. After install, dab over any chip-out from screw removal, the visible caulk line edges, and any spots where the new storm flange exposes raw casing. A small artist brush works better than a roller for this. This is the step that makes the install look intentional rather than retrofit.

For comparison, fully professional install of equivalent custom storms in CT runs $900 to $1,400 per window all-in, or roughly $2,700 to $4,200 for the same three openings. The DIY install on the Allied units saves $900 to $1,700 and is well within beginner-to-intermediate skill range.

Sequencing note: Dennis's exterior paint quote is unchanged by this project. No scope adder, no coordination, no bundled work. Storm replacement happens entirely after Dennis demobilizes and his paint has cured (at least 30 days).

What Could Go Wrong

Dennis's job slips, the storm install slips with it

Storm install happens after Dennis demobilizes plus 30 days of cure time. If Dennis's job pushes to late summer, the storm install pushes to late fall, which is colder and wetter weather for caulk to set. Summer venting gets lost this year regardless.

What to look for Dennis hedges on a firm start date, his quote is more than 60 days old without renewal, or his August schedule is already booked with other clients pushing this work into October.

Mitigation Get Dennis's start and end dates locked in writing before doing anything else. Allied lead time is short enough (3 to 4 weeks) that you can wait until Dennis is nearly done before placing the order. If install lands in cold weather, use a cold-weather rated polyurethane caulk (Loctite PL Premium Max works to 20°F) rather than standard exterior caulk.

Measurements off by 1/8 inch and the storms don't fit

Allied's tolerance is tight on custom units. Off-square openings on a 190-year-old house are normal, not exceptional. A misordered storm becomes a $500+ paperweight you can't return.

What to look for Any opening measures more than 1/4 inch difference between top, middle, and bottom widths, or between left, center, and right heights. Visible racking or sag in the casing also signals trouble.

Mitigation Measure twice. Photograph the tape against the casing at each measurement point. Have Allied review your dimensions before production. For any opening more than 1/4 inch out of square, note it on the order so they build slightly oversized with shimming room.

Window C turns out to be a different size or style than A and B

Only two of the three windows are pictured. If Window C is a different vintage, has a screen panel where the others have storm panels, or sits in a deeper jamb, the order needs to reflect that or you end up with one storm that doesn't fit.

What to look for Visit Window C and check sash count (4 over 4, 6 over 6, 2 over 2), exterior frame profile, jamb depth, and rough opening dimensions against A and B before any measurements get sent to Allied.

Mitigation Walk all three openings with Dennis on day one of his job. Photograph each one from inside and outside. If C is materially different, treat it as a separate Allied order line item with its own dimensions and color spec.

Interior sashes are worse than visible from outside

Lead paint chipping is the surface symptom. Underneath could be cracked glazing, broken sash cords, or rotted bottom rails. None of that kills this project, but it changes Dennis's interior scope and could push his timeline.

What to look for Visible cracking in the glazing putty, sash that won't stay open without propping, or soft wood at the bottom rail when Dennis exposes the interior side. Especially relevant for the wavy-glass originals you want to preserve.

Mitigation Ask Dennis to do a quick interior assessment during his initial visit, before he starts. Price interior sash repair as a separate line item on his quote so any surprise scope shows up explicitly.

Storm finish color doesn't match Dennis's exterior paint

Allied offers a finite set of factory color matches. Since Dennis paints first and you order Allied storms later, this is actually easier than it sounds. You'll know his exact final color before placing the order. Risk only materializes if Allied can't match his color or you order before confirming.

What to look for Dennis using a custom paint mix (anything outside Sherwin-Williams or Benjamin Moore historical lines) that Allied's factory finish library may not match. Or you placing the Allied order before Dennis has applied his final coats.

Mitigation Get a paint chip from Dennis's actual finish coat before placing the Allied deposit. Request Allied's full color chip set and match to that chip. If exact match isn't possible, default to a slightly darker bronze or putty so the storm reads as recessed shadow rather than a bright stripe.

Dennis's storm reinstall complicates later removal

Dennis's standard scope reinstalls the existing storm windows after painting. If he does this with heavy caulk, oversunk fasteners, or galvanized screws that strip on removal, removing the existing storms later turns into a chiseling project that risks chipping the freshly painted casing.

What to look for After Dennis demobilizes, inspect each storm. Heavy caulk bead locking the storm to the casing? Fasteners driven flush with the painted surface? Galvanized rather than stainless screws? Any of those make removal harder.

Mitigation Tell Dennis explicitly during quote renewal: existing storms are coming off again later. Ask him to use stainless screws he can back out cleanly, run a moderate caulk bead rather than a heavy one, and not drive fasteners deeper than necessary. Worth a 5-minute conversation upfront. If you find a problem reinstall later, score the caulk perimeter with a utility knife before attempting removal.

Devil's Advocate

A more ambitious version of this project: rip and replace the entire exterior window assembly (storm housing, exterior casing, sill, jamb extensions, weather barrier) while preserving the original wood interior sashes and their wavy old glass. The interior side of the house stays exactly as it is. The exterior side becomes a clean, modern, fully-sealed assembly that doesn't need a storm window at all.

This is a real preservation strategy and it's the right call if you want to permanently solve the lead paint problem on the exterior, gain meaningful thermal performance, and not be on the seasonal storm window treadmill. You keep the part of the historic window that actually matters (the original sash and wavy glass viewed from inside), and you let go of the part that doesn't (the failing aluminum storms and the lead-painted exterior casings that need maintenance every 10 years).

Cost is the catch. Per-window all-in runs $3,500 to $7,000 when you include exterior carpentry, custom millwork to match the historic profile, integrated weather barrier, and a finish carpenter who knows how to do this without disturbing the interior sash. Three windows is a $10K to $20K project, not a $2K project. It also means committing to a finish carpenter and possibly an architect, not just Dennis and a storm window vendor.

Worth knowing this exists as the right answer if you ever do whole-window restoration on the Old House. Not the right answer for this project, this summer, this budget.

Next Actions

Call Dennis to bundle the storm scope into his quote

Confirm active EPA RRP certification. Confirm he can absorb the storm scope (removal, casing prep, lead-safe paint, interior sash repaint, final touch-up after install). Ask for an explicit scope adder line item with per-window pricing so it's not buried in his exterior total.

Walk all three windows with Dennis on day one

Confirm Window C is pictured-equivalent to A and B, or document the differences. Photograph each opening from inside and outside. Pin Dennis's exterior paint color before you place any Allied order so the storm finish can be matched.

Email Allied Window for an initial quote

Project context: 1830 historic home, three bedroom-level openings, target color matched to Dennis's exterior, screen integrated, ship to Litchfield CT. Ask for a sample quote based on a single window dimension while you wait for Dennis to expose the casings. This builds the relationship before you need to move fast.
