A construction answering service picks up when you cannot: live people, a virtual receptionist or software that answers and books. For a general contractor, the important calls are new project inquiries buried among everything else. This guide covers the options, published prices, what a construction caller needs and how to choose.
- A general contracting customer who gets voicemail usually moves on to the next name. Speed decides more jobs than price.
- General Contractor calls bunch up around late winter bidding through the fall building season. Price any answering service against that stretch, not your average month.
- Voicemail, live people or AI: whichever you choose, it should book into your real schedule and only reach you for the calls you say matter.
- The coldest weeks, when sites slow down is for follow-ups and commercial work. The same system that answers calls can help fill those weeks.
Why general contracting calls are hard to cover
- The phone never stops. Subs, suppliers, inspectors and clients all call the same number.
- New inquiries are worth a lot. One missed call can be a whole addition.
- Clients interview several contractors. The first to book a meeting often sets the tone.
- Job sites are loud. Saws, compressors and concrete trucks drown out the ringer.
If a caller reaches voicemail, many hang up and call the next company on the list. Our guide to what a missed call costs shows how to put a number on that with your own figures.
When the phone rings for general contractors
Most callers are owners planning a major project who interview several builders and want a fixed scope, a real schedule and permits handled. You will also hear from small business owners leasing space, commercial property managers and real estate investors, plus architects, structural engineers, interior designers and the subcontractors you trust sending work your way.
| Month | Pace | What callers want |
|---|---|---|
| January | Get ready | Design meetings and permit drawings |
| February | Get ready | Bids for spring starts |
| March | Busy | Foundations and framing begin |
| April | Busy | Additions under way |
| May | Busy | Framing, roofing and rough-ins |
| June | Busy | Inspections and summer build-outs |
| July | Busy | Finish work and new starts |
| September | Busy | Getting dried in before winter |
It goes quiet in the coldest weeks, when sites slow down. That is when an answering setup sized for the rush costs the most for the least.
Your three options
For general contractors, the deciding question is who replies first while the customer is still comparing. There are three ways to cover it.
Voicemail costs nothing but books nothing, so text every missed caller back fast. A live service puts trained people on your line, answering in your name; they handle unusual calls well and cost the most. An AI receptionist answers or texts back at once, at any hour, offers open times from your schedule and passes anything unusual to you.
What answering services cost
Here are published plans from live and AI services, side by side, with the same columns for every row:
| Service and plan | Price a month | What is included | Past the allowance | Per-person fee | Card payments |
|---|---|---|---|---|---|
| Smith.ai Starter (live) | $300 | 30 calls | $11.50 a call | Not listed | $1.00 a call to take a payment |
| Rosie Professional (AI) | $49 | 250 minutes | Not listed on its pricing page | Not listed | Not listed |
| Goodcall Growth (AI) | $129 | 500 unique callers | 26 cents a caller | Not listed | Not listed |
| Koira Grow (AI receptionist and text-back) | $249 | Receptionist, text-back, booking by text, site, estimates, invoices, campaigns | Usage at cost: texts, call minutes and emails | None: same price with one person or fifteen | Stripe 2.9% + 30¢, plus Koira keeps 1% |
Smith.ai's overage is $11.50 a call on Starter, $10.50 on Basic and $8.50 on Pro. Every published plan we found, plus a worked example, is on answering service cost.
What a general contracting caller needs
- New project inquiry. Scope, address, timeline and budget range if they share it. Book a meeting.
- Current client. A question about the schedule or a selection goes to the project lead the same day.
- Subcontractor or supplier. Take the job name and pass it on.
- Inspector. Pass it on right away with the job address.
- Architect or designer referral. Flag it; these are often the best leads you get.
- Price shopper. Share honest ranges and offer a meeting.
Write these down once, with what counts as an emergency for your shop. That is the script for a live service and the playbook for software. Our post on after-hours calls covers sorting calls into tonight and tomorrow.
What to ask before you sign up
- Can it book into my real schedule instead of just taking a message?
- What happens around late winter bidding through the fall building season? Ask about hold times when every line rings, and about overage pricing.
- Will callers hear my business name, and can it handle Spanish?
- What will it never do? It should never quote a price you did not set.
- Can I leave any month, and does adding help cost more?
How Koira's AI receptionist handles general contracting calls
When you cannot answer, Koira's receptionist texts the caller within about a minute, asks what they need and offers three times that fit your day. The booked visit shows up with the address and the details. A caller who wants a structural repair can be offered times from your list; a question about a second-story addition comes to you to price. It answers in English or Spanish, never invents a price, and only a price, a complaint or an emergency reaches you; at night it texts you only for what you marked as an emergency.
Koira Grow is $249 a month plus usage at cost: texts, call minutes and emails with nothing added. Adding a helper never adds a seat fee; the price is the same with one person or fifteen. Booking by text picks times that suit the route you already have.
Use the quiet weeks
Midwinter is for planning. Follow up every open proposal, ask past clients for referrals and check in with the architects and designers who send you work. Koira's bid follow-ups and referrals run on Grow. More on Koira for general contractors and what each plan includes.
