Window & Door Installation Software. Built by construction pros with honest pricing.

What Is Window and Door Installation Software?

Window and door installation software is a project management platform built for contractors who measure, order, and install windows and doors. It connects field measurements, custom unit orders, lead time tracking, crew scheduling, and invoicing so nothing gets lost between the tape measure and the finished install.

Projul’s window and door installation software helps installers connect field measurements, custom unit orders, and lead time tracking in one platform built by construction professionals who understand precision installation workflows. Projul offers flat-rate pricing with no per-user fees for construction companies of all sizes.

If you run a window and door installation company, you already know that the margin for error is razor thin. One wrong rough opening measurement means you eat the cost of a custom unit. One missed lead time means your crew shows up with nothing to install. One undocumented damage claim means you pay for a scratch you did not cause.

Window and door installation software like Projul exists to keep every detail tied to the job record so your office and your field crews work from the same information. No more ordering from a text message. No more guessing when units will arrive. No more scrambling for energy code paperwork the morning of inspection.

Protect Your Margins on Every Custom Order

One wrong rough opening measurement and you eat the cost of a custom unit. That is the reality of running a window and door installation business. A single mis-order on a large casement window can cost you $800 or more, and the manufacturer is not taking it back.

Projul keeps your field measurements, custom orders, lead times, and install schedules tied together so expensive mistakes stay rare. Over 5,000 contractors rely on Projul to protect their margins on every job. Window and door installation software should prevent problems, not just track them after the damage is done.

Most ordering mistakes happen because the field measurement lives in one place and the order form lives in another. Your installer texts a measurement to the office. The office writes it down, maybe transposes a digit, and places the order. Three weeks later, the wrong size shows up on the truck. With Projul, the measurement, the photo, and the specs all live on the job record. Your office orders from the same data your installer captured on site.

Tie Field Measurements to Every Job Record

Projul ties rough opening dimensions, jamb extension specs, and photos directly to each job record. Your office orders exactly what was measured on-site instead of trusting a text message or a handwritten note.

Here is what that looks like in practice. Your installer measures a rough opening at 36-1/4 by 72-1/2. They snap a photo showing the existing frame condition, note that the jamb extension needs to be 6-9/16 for 2x6 wall construction, and specify brick mold on the exterior. All of that information lives on the job in Projul. When your office places the order, they reference the exact same record. When the units ship, the warehouse team checks the delivery against the specs on the job.

Window and door installers using Projul cut ordering mistakes and report a 32% average profit increase from eliminating costly mis-orders. That number makes sense when you consider that a single custom patio door can run $2,000 or more. Getting the order right the first time is not just convenient. It is the difference between profit and loss.

Unit Counts and Sizing for Multi-Window Projects

On a whole-house window replacement, you might have 15 to 25 openings with different sizes, styles, and configurations. Keeping that organized on a spreadsheet works until it does not. One transposed number in row 14 means a bathroom window shows up as a bedroom window, and your schedule slips while you wait for the replacement.

Projul lets you create line items for each opening with dimensions, style (double-hung, casement, slider, picture), and any special notes like tempered glass for egress or obscure glass for bathrooms. Your entire order lives in one place, and anyone on your team can check it.

Track Lead Times on Custom Window and Door Orders

Custom window orders carry lead times that range from two weeks to twelve weeks depending on the manufacturer, the finish, and whether you ordered a standard size or something unusual. Miss that delivery window and your install crew sits idle while you burn payroll.

Projul lets you create tasks with expected delivery dates for each custom unit and sends reminders as deadlines approach. When a manufacturer pushes a mulled unit delivery back three weeks, you update the task and the install schedule adjusts with it. Your crew never shows up to a site with no product on hand.

Material Ordering for Custom Sizes

Ordering materials for window and door installation is not like buying lumber at the yard. Every unit is built to your specifications. That means your order has to be perfect because returns are either impossible or expensive. Projul’s window and door installation software keeps the specs, the order confirmation, and the delivery date all on the same project record. When you are managing orders from multiple manufacturers across multiple jobs, that single source of truth saves you from the chaos.

Track which units are on order, which have shipped, and which are sitting in your warehouse waiting for install day. Your office stops calling the manufacturer for status updates because the information is already in the system.

Removal and Disposal of Existing Windows

On replacement jobs, the old windows have to come out before the new ones go in. That sounds simple, but removal adds time, labor, and disposal costs that eat your margin if you do not account for them.

Projul lets you build removal and disposal into your estimate templates as separate line items. Track the labor hours your crew spends on tear-out separately from installation hours. Log disposal costs, whether you are paying a dumpster fee or hauling to the landfill yourself. This level of detail in your window and door installation software means your estimates reflect the true cost of the job, not just the cost of the new units.

For lead paint situations on pre-1978 homes, document your RRP compliance steps right on the job record. Photos of containment setup, HEPA vacuuming, and clearance testing all go on the project file. When EPA compliance is on the line, having that documentation beats trying to recreate it from memory.

Energy Efficiency Upgrades and Code Compliance

Energy codes are getting stricter every cycle. The 2021 IECC requires U-factor ratings that older windows cannot meet, and many states have adopted even tighter standards. Your clients are asking about energy savings. Their utility companies are offering rebates. The inspector is checking NFRC labels.

Projul stores U-factor ratings, Solar Heat Gain Coefficient (SHGC) values, low-E glass specifications, and NFRC label data on each project record. When the inspector asks for documentation, you pull it up on your phone. Energy code compliance paperwork is never a last-minute scramble because it lives right on the job.

For contractors who sell energy efficiency upgrades, this documentation also helps you show homeowners the before-and-after performance numbers. A client who can see that their old single-pane windows had a U-factor of 1.2 and their new units are at 0.25 understands exactly what they are paying for. That transparency builds trust and generates referrals.

Window and door installation software that tracks energy specs is not optional anymore. It is how you stay compliant, win better jobs, and protect yourself during inspections.

Permit Requirements for Window and Door Work

Permit rules vary by jurisdiction, but many cities require permits for window replacements, especially when you are changing the size of an opening or adding new egress windows. Forget to pull a permit and you risk a stop-work order, a fine, or a callback months later when the homeowner tries to sell and the title company flags unpermitted work.

Projul lets you track permit status as part of your project workflow. Note when the permit was applied for, when it was approved, and when the final inspection is scheduled. Your office sees the permit status at a glance, and your installer knows whether the job is cleared to start before they load the truck.

For new construction work where the GC handles permits, you can still track your inspection requirements. Log when the window install needs to be inspected for flashing, sealant, and energy code compliance. Keep the inspection result on the job record so there is no confusion about whether you passed.

Warranty Tracking That Protects Your Reputation

Windows and doors carry manufacturer warranties that can last 10 to 20 years. Your labor warranty might cover one to five years. When a homeowner calls about a failed seal or a broken balance two years after installation, you need to know exactly what was installed and what is covered.

Projul stores warranty details, manufacturer information, and installation dates on each project record. Pull up the job, see which units were installed, check the warranty terms, and give your client a clear answer instead of fumbling through old paperwork. Contractors using window and door installation software with warranty tracking resolve claims faster and keep their reputation strong with both clients and manufacturers.

This also matters for commercial jobs where property managers track warranties across hundreds of units. When building management calls about a failing unit on the third floor, you can pinpoint exactly which product was installed, when, and by which crew.

Commercial vs. Residential Window Installation

Running both commercial and residential window work from one company means managing two very different types of projects. Residential replacements involve homeowner schedules, design choices, and individual attention. Commercial jobs involve unit counts in the hundreds, GC coordination, and punch list processes that can drag on for weeks.

Projul handles both from one platform. For residential work, you manage the full process from the sales appointment through the final walk-through. For commercial projects, break the scope into floors, wings, or sections. Assign different crews to each area and track unit counts across the entire building. Your window and door installation software should flex to match your project mix, not force you into one workflow.

Commercial work also means coordinating with other trades. Your install might depend on the framing contractor finishing rough openings to spec, or the stucco crew needing your units set before they can start exterior work. Projul’s scheduling tools show where your work fits in the overall build sequence so you can plan around dependencies instead of reacting to surprises.

Document Damage Claims With Timestamped Photos

Crews upload timestamped photos before, during, and after every install directly from the job site. If a client claims a scratch on a casement window was your fault, you have documented proof of the unit’s condition at delivery and after installation. This alone has saved Projul users thousands in disputed damage claims.

Window and door units are expensive and fragile. A patio door with a scratch in the glass costs over $1,000 to replace. Without photo documentation, it is your word against the homeowner’s. With Projul’s window and door installation software, your crew documents every unit at delivery and after installation. The photos carry timestamps and GPS data that prove when and where they were taken.

This protection extends to transit damage as well. When units arrive from the manufacturer with a cracked frame or chipped glass, your crew documents the damage immediately in Projul. The manufacturer claim process goes smoother when you have photographic evidence logged the day of delivery instead of filing a complaint two weeks later from memory.

Estimating That Wins More Window and Door Jobs

Your estimate is the first thing a homeowner sees from your company. A sloppy bid on a plain email does not inspire confidence for a $15,000 whole-house window replacement. A clean, itemized estimate from Projul shows the client exactly what they are getting and positions you as the professional choice.

Build estimate templates for your most common jobs. A standard double-hung replacement, a patio door swap, a full-house package. Each template carries line items for units, labor, removal, disposal, trim, caulking, and any energy code compliance work. Adjust quantities for each new job and send the estimate out looking sharp. When the client approves, that estimate converts directly into a scheduled project with job costing already built in.

Window and door installation software with strong estimating tools means more bids out the door and a higher close rate. Contractors using Projul report cutting their estimating time in half, which means more appointments and more signed contracts.

Scheduling Installs Around Client Availability

Residential window installation requires access to the home. That means coordinating with the homeowner’s schedule, which is not always simple. Some clients work from home. Others need to take a day off. A no-access situation means your crew sits in the driveway burning daylight.

Projul’s scheduling tool lets you set install windows that work for both your crew and the client. Share calendar views, send appointment confirmations, and reschedule with drag-and-drop when plans change. Your window and door installation software should minimize no-access delays so your installers stay productive.

For multi-day installs, break the project into daily tasks. Day one might be first-floor removal and install. Day two handles second-floor work and exterior trim. The client sees the plan, your crew knows the sequence, and everyone stays on the same page.

Job Costing That Shows Your Real Numbers

Every window and door job has a target margin. Without real-time job costing, you find out whether you hit that margin after the job is done. By then, it is too late to fix anything.

Projul tracks estimated costs versus actual costs on every project. See where your labor hours are landing compared to your bid. Check whether material costs matched your estimate or whether that upcharge on custom trim blew your budget. Window and door installation software with live job costing lets you catch overruns at job three of a ten-job week instead of discovering the problem during your monthly review.

Contractors using Projul report a 32% average increase in profitability. That comes from catching cost issues early and keeping every job on track.

Your Installers Manage Every Job From Their Phone

Your window and door crews move from house to house and need measurements, specs, and schedules at their fingertips. Projul’s native mobile app lets them check rough opening dimensions, upload before-and-after photos, and log hours with geofencing at every stop.

If a custom unit arrives damaged, your crew documents it on the spot with timestamped photos and notifies the office before the homeowner has to ask what happened. If the rough opening does not match the specs on file, they flag it immediately so your office can address it before the install continues.

The app works on dusty phones with one bar of signal. Your crew uses it by lunch on day one because it was designed for the field, not for a corner office. That adoption rate is why G2 users rate Projul 9.8 for ease of use.

Honest Pricing for Window and Door Contractors

Projul starts at $4,788 per year for your entire window and door company. No per-user fees. Your estimators, crew leads, office staff, and installers all get full access without inflating the bill.

Most window and door installation software charges per user. That pricing model punishes you for growing. Hire another installer? More money. Add a sales rep? More money. Give your warehouse manager access to check deliveries? Even more money. Projul’s flat rate means your 20th employee costs the same as your 5th.

Over 5,000 contractors use Projul to manage their operations, and window and door contractors consistently report saving 2+ hours daily on admin work. G2 users rate Projul 9.8 for ease of use and 9.8 for quality of support.
