Angi Alternatives for Windows & Doors Contractors (2026)

The strongest Angi alternatives for windows & doors contractors are theBuildd for exclusive, phone-qualified residential leads; Modernize for broad documented scale; 99 Calls for managed window-specific acquisition; Inquir and 33 Mile Radius for exclusive delivery; and Google Local Services Ads for direct search demand. None proves useful volume in your ZIP codes.

Disclosure: theBuildd publishes this comparison and sells exclusive windows and doors leads. We rank theBuildd first on one-buyer delivery, phone qualification, protected territory, speed and replacement terms. Modernize and 99 Calls publish stronger platform-scale signals, and we say so plainly.

How we compared these Angi alternatives

We checked provider-owned contractor pages, consumer pages, pricing pages, help documents and terms on 20 August 2026. An alternative qualified for the shortlist only when it published a windows or doors scope and a repeatable acquisition model. We compared lead ownership, qualification, delivery, targeting, public pricing or terms, scale evidence, invalid-lead remedy and replacement-versus-repair fit.

First-party pages were accepted as evidence of what each provider says it offers, not as proof that one offer performs better. National platform totals counted as acquisition capacity, not local supply. A regulatory claim required a regulator’s record plus the named company’s response. When public evidence did not establish local volume, a window-only count or a price, we marked it unknown instead of estimating it.

The trade-scoped shortlist, ranked

A real Angi windows and doors alternative must cover the work, not merely list “home improvement” on a sales page. It also needs a repeatable acquisition system, documented distribution rules and enough targeting control to separate whole-home replacement from a broken pane or single-door repair.

This ranking gives the greatest weight to provider-created competition and screening work, which is why theBuildd leads. A buyer weighting published national scale above exclusivity should place Modernize or 99 Calls first. The broader Angi alternatives comparison covers vendors without this trade filter.

Volume evidence separates a replacement from a supplement

“At volume” should mean more than a nationwide map. It requires two proofs: the vendor runs a repeated acquisition system for window or door projects, and it can show recent supply for the job types and ZIP codes the contractor actually accepts.

No public page can establish the second proof. Modernize says it qualifies more than 40,000 homeowners weekly and more than 2 million annually, but those are company-wide figures. Its dedicated windows program proves trade coverage, not the number of replacement-window opportunities available in one market.

99 Calls displays more than 1.4 million leads generated across its business and runs a specific window-installation offer. Its scope includes sliding-door replacement, but the page is far deeper on windows than entry, patio or interior doors. A door-heavy contractor should not import window capacity into a different service line.

theBuildd’s typical range is 10 to 15 qualified leads a week, depending on trade, territory size and local demand. It is not a guaranteed floor or a windows-only national average. Check the current windows and doors coverage and ask for local availability before treating the range as a replacement plan.

Angi covers the trade, but its terms preserve competition

Angi clearly covers window and door work. Its current national contractor page includes new windows by quantity, exterior-door installation or replacement, screens, repairs and related projects. The page checked for this review offered to match the homeowner with up to three pros; current city pages can display up to five.

That consumer-facing range is consistent with the current Angi Pro Agreement. Version 1.4, effective May 12, 2026, says a lead is frequently sent to several Approved Pros. It also says sales and onboarding lead-volume guidance is an estimate, not a promise.

Angi’s genuine gain is breadth. A contractor can appear for several related tasks, maintain a public profile and tap a large homeowner network. The loss is control over recipient count and screening labor. Angi says it makes connections; it does not describe every lead as a one-buyer, phone-qualified appointment.

The FTC order still belongs in a 2026 switch decision

In January 2023, the Federal Trade Commission announced an order involving HomeAdvisor, an Angi-affiliated company. The order required HomeAdvisor to pay up to $7.2 million and stop deceptively marketing home-improvement leads.

The FTC complaint alleged false, misleading or unsubstantiated claims about lead quality and source dating to at least mid-2014. It addressed service and geographic matching, whether homeowners had asked HomeAdvisor directly for help, and representations about how often leads became jobs.

HomeAdvisor disputed the allegations. An Angi spokesperson called them “outrageous” and described the suit as “meritless,” arguing that the FTC relied on a small, cherry-picked set of sales calls and overlooked the value delivered to contractors.

That rebuttal belongs beside the regulator’s record. The order does not prove that every current Angi window lead is unsuitable. It does justify a stricter buying process: compare the sales claim, current pro terms and exact order, then keep whichever promise is narrowest and written.

What each Angi alternative changes

1. theBuildd removes seller-created competition

theBuildd sends each residential homeowner lead to one buyer and never shares, resells or recycles it. A five-person in-house team calls every homeowner, checks consent and project intent, then sends accepted leads by text and email in under 10 minutes. Territory is locked by ZIP code and trade.

Bad leads are replaced. The honest caveat is availability: the desired windows and doors territory may already be assigned. theBuildd also does not qualify commercial projects, promise a weekly floor or return cash in place of its replacement remedy.

Ask for the accepted window and door scopes, ZIP codes, exclusivity and replacement terms in writing. Take this list to every provider you talk to, including us. Published plans and trial pricing make the spend visible before that conversation.

2. Modernize has the clearest broad scale signal

Modernize’s windows program lists vinyl, wood, fiberglass, impact-resistant, storm, retrofit and full-frame projects. It offers standard leads, inbound calls and live transfers. The company says its call center prequalifies live transfers, while standard form details go to a contractor for follow-up.

Its strongest advantage is acquisition breadth. Modernize publishes a large cross-trade qualification count and supports call-center teams, CRM delivery and location targeting. Its consumer FAQ says a quote request can match with up to four contractors, so standard leads are not a clean one-buyer replacement.

Doors need separate confirmation. Modernize lists doors in its affiliate inventory, but its contractor-facing windows page does not document door products with the same depth. A combined installer should require separate capacity and pricing for each service line.

3. 99 Calls turns acquisition into a managed system

99 Calls publishes a dedicated window-installation program using organic search, Google Ads and, where available, Local Services Ads. It names window replacement, installation, repair, storm windows and sliding-door replacement, and says each lead goes to one company.

This is a larger operational change than buying another contact feed. The contractor gains a managed website, listings, advertising and CRM tools, depending on the package. It also takes on channel ramp time, campaign dependence and the need to distinguish which assets and accounts remain under contractor control.

4. Inquir sells a detailed exclusive record

Inquir’s windows-and-doors page is unusually specific about the delivered data. It lists project type, quantity of windows or doors, installation timeline, homeownership confirmation, contact preference and proof-of-consent records. It says each lead comes from its owned Renovate Co site and goes to one buyer.

The gain is precise filtering and pay-as-you-go delivery without a published minimum. Pricing starts at $45 on the current contractor offer, which also publishes a $45–$120+ range based on targeting and volume. The caveat is the qualification method: phone, email and identity validation can improve contactability, but they do not establish that a person discussed scope and intent with the homeowner.

Its “high-volume support” is a capability claim, not a local supply count. Ask for recent delivery by repair, replacement, windows, doors, quantity band and ZIP code before assigning it the full Angi budget.

5. Google Local Services Ads captures direct search demand

Google officially lists window repair as an eligible US Local Services Ads category. Its definition includes installation and repair of windows and may extend to doors, skylights and other glass. Advertisers can choose job types and service areas, subject to local eligibility and verification.

The contractor gains control of the profile, targeting, budget and lead record. The contractor also owns reviews, account maintenance, screening and response coverage. Google does not promise protected territory, a windows-and-doors volume floor or a phone qualification conversation before every contact.

This channel fits repair and installation demand that maps cleanly to Google’s available job types. A replacement dealer should inspect the live account options rather than assume a broad “window repair” category will expose every whole-home or specialty-door project.

6. 33 Mile Radius offers exclusive calls with a document caveat

33 Mile Radius expressly lists whole-home window replacement, vinyl windows, doors and storm windows. It routes live calls to one contractor and publishes no setup fee, monthly fee or long-term contract. Valid leads are billed weekly under its service, authority and location rules.

One detail needs clarification before purchase. The live window-leads page describes the service condition as a request for “bath remodeling or installation services,” which appears inconsistent with the surrounding window copy. That may be a page error, but the accepted order must state the actual billable window and door scopes.

Its 20,000-lead annual claim covers the full partner network, not windows in one territory. Treat 33 Mile Radius as a potentially useful exclusive call source, then let written local availability decide whether it can replace Angi or only supplement it.

A two-lane plan protects the estimator calendar

Windows and doors should not sit in one undifferentiated lead bucket. A whole-home replacement appointment, a single failed seal, an entry-door install and a sliding-door repair use different sales time, field skills and material workflows. One cheap category can hide an expensive mismatch.

What contractors gain and lose by switching

Leaving Angi can remove multi-pro delivery, improve job-type control or put the acquisition assets in the contractor’s account. It can also remove a familiar profile, broad project mix and a single place where homeowners compare providers.

Worked example: cost per sold job from a $45 lead

This illustration uses one published price and two explicit assumptions. It is not a forecast, an industry benchmark or a result reported by theBuildd, Inquir or any contractor.

Lead spend: L × P = 8 leads × $45 per lead = $360.

Sold-job share: J ÷ L = 1 sold job ÷ 8 leads = 0.125 sold jobs per lead, or 12.5%.

Cost per sold job: (L × P) ÷ J = $360 ÷ 1 sold job = $360 per sold job. The rate form produces the same result: $45 per lead ÷ 0.125 sold jobs per lead = $360 per sold job.

The 12.5% sold-job share is calculated from the two assumptions, not presented as a realistic close-rate claim. Replace L and J with one provider cohort from your CRM. Add staff time, membership, setup, management and ad-spend charges when they apply, because the worked result includes lead charges only.

The invoice will never tell you that. Compare total spend with reached homeowners, qualified replacement opportunities, held measurements, issued quotes, sold jobs and gross margin. The contractor lead-cost framework explains why contact price alone is the wrong scoreboard.

A controlled exit takes six steps

1. Split the last Angi period by project. Separate repair, single-opening installation, multi-window replacement, whole-home replacement, entry doors, patio doors and work you would decline today.
2. Define the capacity that must survive. Record estimator slots, install capacity, staffed response hours, serviceable ZIP codes and minimum project scope. Do not buy a larger map than the team can serve.
3. Request recent local supply. Ask each provider for availability by project type and ZIP. Treat every national volume figure as background until that answer arrives.
4. Write the buying rules. Put recipient count, resale, source, qualification, delivery, billable event, invalid-lead remedy, term and exit language in the order. Compare the vendor against all supported trades if you sell adjacent exterior work.
5. Run a bounded overlap. Keep Angi active while one replacement lane and one repair lane produce enough actual estimates to expose scope errors and operational gaps.
6. Move spend from outcomes. Compare held measurements, issued proposals and sold work under fixed source definitions. Reduce Angi only when the replacement mix supports the calendar.

That is really all there is to it. The best windows and doors lead source is not the one with the largest company-wide number. It is the source that repeatedly fills the right estimator slots, under written distribution and qualification rules, in the territory your crews can serve.

See the exclusive-lead alternative

theBuildd fits residential windows and doors contractors who want one buyer per lead, a human qualification call and a territory defined by ZIP code and trade. It is not the right choice for commercial projects, guaranteed weekly volume or a buyer requiring cash back instead of replacement.
