For window, door & siding contractors
For window, door & siding contractors who are on a ladder when the phone rings.
Replacement windows, entry doors, and siding are big jobs, and homeowners usually get more than one bid. If you're slow to call back or let a bid go quiet, you can lose the job to whoever got back to them first. Mainline Systems catches the callers you miss, emails you their voicemail transcribed, lines up the measure request, and follows up on your proposal. It runs on your existing number, and every email goes out in your business's name.
A day on the tools
Where the work slips away.
You can’t be on the tools and on the phone at once. These are the moments that cost window, door & siding contractors jobs.
-
You're up on staging or setting a window when the phone rings. By the time you call back, the homeowner has booked a measure with someone else.
-
Window and siding jobs get shopped around. Bids sit for weeks while the homeowner compares numbers, and nobody on your crew has time to follow up.
-
A missed-call voicemail doesn't tell you how many windows, what kind of siding, or how old the house is, so you drive out without knowing what you'll find.
-
Homeowners forget measure appointments, and you lose an hour of driving to a locked door.
-
Custom windows and doors can take a long time to arrive. Customers who hear nothing between the order and the install start calling to ask where things stand.
-
Finished jobs rarely turn into Google reviews because by the time the customer is happiest, you're already at the next house.
The same day, with Mainline Systems running
It's a wet Tuesday in November. A homeowner in Beaverton has noticed fog between the panes of three living-room windows and a draft at her back door. At 10:40 she calls a window contractor. He's on a ladder in Tigard setting a slider and can't answer. She hears his greeting and leaves a voicemail: three windows and a door, house built in the 1960s, wants it done before spring. He gets the transcript by email, calls her back at lunch, and sets a measure for Thursday. After the measure he uploads his estimate to the proposal page. She opens it that night and sends a question about grid patterns, which goes straight to him. When a few days pass without a decision, a polite follow-up email goes out. The follow-ups stop when she approves the estimate.
How it helps
What Mainline Systems handles for window, door & siding contractors.
It runs on the number you already have. It never quotes a price and never diagnoses a problem. Those go to you.
-
Missed-call recovery
When you can't pick up, the caller hears a greeting in your business name and leaves a voicemail, and you get the transcript right away. Texting turns on once carrier approval clears.
-
Leads in the customer's own words
Windows, doors, siding or trim, sorted for urgency, so you know the job before you call back.
-
Measure requests
Web customers pick a preferred window and you confirm it with one tap, then they get the confirmation and reminders by email.
-
Proposal page
The homeowner can view your estimate (your own bid, uploaded from your phone) and approve it, decline it, or ask a question from their phone. A Good/Better/Best builder is coming in December.
-
Estimate follow-up emails on day 1, 3 and 7. They stop as soon as the homeowner approves, declines, or asks a question.
-
Confirmation, day-before and same-day reminder emails for measures and install days.
-
Review requests after the job
Every customer you mark done gets the same link to your Google profile. We don't filter out unhappy customers.
-
Included
About six months after the job, customers you mark done who have an email on file get a short check-in email in your name asking how the new windows, doors, or siding are holding up and whether anything else is on their list, with the same review link everyone gets.
-
A Customer File in your phone app that keeps each homeowner's job history, photos, and notes in one place.
Built by a tradesman
Built by a tradesman who’s been in your boots.
Mainline Systems was built by someone who’s worked in the trades, not a software company. We won’t pretend to know your trade better than you do: the system never diagnoses, never quotes a price, and sends every technical question to you. What we do know is the part every trade shares: the phone ringing while your hands are full, and the bid that goes quiet because nobody followed up.
Jobs it’s set up for
Set up for the work you actually do.
We tune the list to what your shop takes on. A typical starting point:

What window, door & siding contractors ask us
My jobs are big and shopped around. Will automated follow-up make me look pushy?
Three follow-up emails (day 1, 3 and 7), written in plain language, that stop as soon as the homeowner approves, declines or asks a question.
Will the system quote prices or tell customers what kind of window or siding they need?
No. Prices, product recommendations, and technical questions go to you. The system is set up not to send prices or diagnoses.
Why does the build year matter?
Homes built before 1978 may have lead-based paint. Under federal and state rules, paid work that disturbs paint in those homes generally has to be done by a certified firm using lead-safe practices, and window replacement is always covered. Knowing the build year before the measure helps you plan and staff the job. When it comes up in a voicemail or form, it's in the job notes. The system doesn't give any advice about lead.
Do you work with siding-only or window-only shops?
Yes. We write the greeting and email wording to match what you sell, whether that's windows only, entry and patio doors, siding and trim, or all of it.
What happens if someone calls about a break-in or a shattered window?
Your greeting tells callers to hang up and dial 911 in an emergency, and a voicemail about a break-in or broken glass is flagged urgent so you're alerted right away. You decide whether to send someone to board it up.
Who gets asked for a review?
Every finished customer, the same way. When you mark a job done, everyone gets the same review-request email with the same Google review link. Nobody is screened out first, and nobody is offered anything for a review. If someone is unhappy, you also hear about it privately so you can make it right.
What does it cost, and am I locked in?
It's month-to-month with no long-term contract. We go over pricing on the free audit call.
