When you are working out how to choose a mobile windshield replacement company, ask each one which records it will hand you and which it will keep. A van in your driveway has no storefront to judge, so the paperwork is the proof. That means the adhesive and glass traced to your job, a stated drive-away time, an itemized list of the work, and a clear answer on camera recalibration. Each item comes from a published safety standard or a state statute, so you can ask for it by name.
How to Choose a Mobile Windshield Replacement Company From Its Records
| What to Ask For | Where the Rule Comes From | When You Should See It |
|---|---|---|
| The name of the adhesive system, and whether the vehicle maker approves it or its own maker vouches for it in writing | AGRSS standard, 2015 edition, section 5 | Before the work starts |
| Adhesive lot numbers tied to your job | AGRSS standard, section 6 | In the installer's job record |
| The glass DOT number and part number tied to your job | AGRSS standard, section 6 | In the installer's job record |
| Confirmation that no product is past its expiration date or shelf life | AGRSS standard, section 6 | Before the adhesive goes on |
| A job record kept at least three years from completion | AGRSS standard, section 8 | Ask at booking |
| The minimum drive-away time | AGRSS standard, section 6 | Before and after the installation |
| An itemized description of the work | A.R.S. 20-463.02(B) in Arizona; Fla. Stat. 559.911 in Florida | Before the work, and on the final invoice |
| Whether camera recalibration is required | A.R.S. 20-463.02(A) in Arizona; Fla. Stat. 559.920(18) in Florida | Not timed in either statute; ask at booking |
| Notice that a recalibration was not performed or did not succeed | A.R.S. 20-463.02(D) in Arizona | When that happens |
| The shop's registration number | Fla. Stat. 559.904 and 559.911 in Florida | On the invoice |
Most of these rows come from the Auto Glass Safety Council's AGRSS standard, 2015 edition, published as ANSI/AGSC/AGRSS 003-2015. Its rules apply to anyone who replaces auto glass. A driveway job is glass replacement like any other, so the same adhesive, tracing and drive-away rules apply to it. Our mobile windshield replacement service brings the glass, urethane, tools and power to the car where it is parked.
The Adhesive System
Start with the adhesive, since it is what holds a bonded windshield in its opening. The standard calls it the retention system. An installer must use a system the vehicle maker approves, or an equal system. In the second case, the adhesive's own maker must vouch for it in writing, directly or through a private labeler. Ask the company to name the urethane system it plans to use on your car. Then ask which of those two routes it meets.
An answer like "a good commercial urethane" does not tell you either one. A company working to the standard can name the product and say whether the approval comes from the vehicle maker or from the adhesive maker's written statement. Write the product name down with the date of the visit.
Lot Numbers, Part Numbers and Shelf Life
Section 6 adds two tracing rules. Every adhesive system component lot number must be traceable to each job. Every glass part must be traceable to the installation by a DOT number and a part number. If a batch of urethane or a run of glass later proves faulty, those numbers are how a single job gets matched to it.
The same section sets a hard limit on age. No product may be used past its expiration date, its open shelf life or its active shelf life. Those limits are the ones its maker or private labeler states. Any one of those three is enough to rule a product out. Ask the technician to show you the dates on the adhesive before it goes on the car.
Training and Records Behind the Van
Buyers often ask first whether the technicians are trained. Section 9 of the standard answers that with a test you can apply. Technicians installing replacement glass must be fully qualified for the tasks they are required to perform. At a minimum, that means finishing a comprehensive training program with a final exam and an ongoing education component.
That turns a vague question about mobile auto glass technician qualifications into three specific ones. Ask which training program the technician completed, whether it ended in a final exam, and what ongoing education keeps it current. A reply about years in the trade answers none of the three. The qualification also covers each task the technician is required to perform, so a technician who handles camera recalibration needs to be qualified for that task too.
Records come next. Section 8 requires installers to create and keep a record of each replacement for at least three years from the date the work was completed. That record has to be detailed enough to show the job met the standard. Lot numbers and the glass DOT and part numbers are the details that let a record show compliance.
For a mobile job, that record is your trail back to the installation if a question comes up a year later. You may never see the company's office, so ask at booking how long job records are kept and whether you can get a copy of yours. Three years from completion is the minimum the standard sets, and a company may keep them longer.
Section 8 also covers bad product found after the fact. If an installed product is found to be defective, or could put the customer's safety at risk, the customer must be told at once. That report must come with an offer to remedy the problem. That report can only reach you if the company has contact details for you that still work after the van leaves. Check that the email and name on your paperwork are right before the technician drives off.
Drive-Away Time Should Be Explained Twice
The standard's drive-away rule has two moments in it. The vehicle owner or operator must be told the minimum drive-away time before the installation starts and again after it is finished. Both notices are tied to the circumstances of that replacement. A figure from a brochure or from someone else's job does not meet the rule.
The first notice lets you plan the day. If you need the car for a school run two hours after the visit, you know before any glass comes out whether that works. The second notice confirms the time for the job as it was actually done. If you hear one figure at the end, or none at all, ask for both.
Drive-away time is the point at which the car can be driven safely after the glass is set. It is not a fixed number that holds for every job. A cure time printed for an adhesive is a lab figure. The technician sets the drive-away time for your car from the product and the conditions where it is parked. Our technician confirms that time for your car before leaving.
The wait itself is covered in our post on how long to wait after a windshield replacement before driving. Rain, heat and cold raise a separate question, the weather limits on a mobile install. Once the time is stated, a few checks you can make yourself are listed in how to spot a bad windshield installation before you drive away.
Where Registration Applies to Mobile Glass Shops
In Florida, a mobile glass company falls under the Motor Vehicle Repair Act. The consumer page on motor vehicle repair from FDACS, the Department of Agriculture and Consumer Services, lists who the act covers. The list runs from new and used car, truck and motorcycle dealers to garages, service stations, self-employed persons and truck stops. It then names paint, body, brake, muffler, transmission, mobile repair and glass shops. A van-based windshield company fits two of those categories at once.
Registration is the first duty. Fla. Stat. 559.904 requires each motor vehicle repair shop to register with the department before doing business in the state. The application asks for the business address where repair work is done. For a mobile shop, it asks for the owner's home address if that differs from the business address. So even a company with no shop floor has an address on file with the state.
FDACS points people to its Business License Lookup to see if a repair shop is properly registered. You can also call 1-800-HELP-FLA (435-7352). Search the company name before you book. Then make sure the name on your quote matches the name on the registration.
In Arizona, the statute written for auto glass facilities is A.R.S. 20-463.02. It sets notice, itemization and billing duties. This article uses it for those three duties. For a job there, your proof is the paperwork that statute requires, plus the standard's records.
Invoices That Carry a Registration Number
Registration shows up again on the paper you keep. Under Fla. Stat. 559.911, the shop must give each customer a legible copy of an invoice upon completion of any repair. One required item is the registration number from the certificate the department issued to the shop.
That number ties the invoice to a registration record you can look up. Look for it when the invoice reaches you, whether on paper or by email. If it is missing, ask for it, then match it against the Business License Lookup.
Expect the windshield replacement invoice to carry an itemized description of all labor, parts and merchandise supplied, with the cost of each. Anything a shop or manufacturer's warranty paid for, in whole or in part, has to be marked as such. On a windshield job, the glass, the adhesive and the labor each belong on that list, along with any other part supplied and any recalibration work.
A list like this makes two jobs easy to compare line by line. The glass DOT and part numbers that the standard traces sit in the installer's job record, and you can ask for them on your copy. The terms we put on our own work are on our warranty page.
Itemized Work and Notices Before the Job Starts
A.R.S. 20-463.02(B) starts the paperwork earlier in the job. An auto glass repair or replacement facility must give the customer an itemized description of the work to be done on the vehicle. The description covers work ahead of the technician, which makes it something to ask for before any tools come out. Compare it with the final bill when the job is done.
Subsection A of the same Arizona auto glass law adds a recalibration notice for any vehicle equipped with an advanced driver assistance system. A facility that does glass repair, replacement or recalibration must tell the customer whether recalibration of that system is required. It must also tell the customer that any recalibration it performs has to meet or exceed the vehicle manufacturer's specifications.
Subsection F sets a billing limit. A facility may not bill the customer, or the customer's insurer, for glass repair, replacement or recalibration work that was not done to the vehicle manufacturer's specifications. Each line on the itemized list should be work done to that manufacturer's procedure. If a recalibration is listed, ask which manufacturer procedure it follows.
Whichever statute applies, you can ask for an itemized windshield replacement estimate at booking. Then check it against the final paperwork. When an insurer is paying, who chooses the glass company when insurance pays is its own question, apart from these notices.
Camera Recalibration Notices When the Job Needs Them
Fla. Stat. 559.920(18) puts the recalibration rule in the Repair Act's list of violations. The shop must tell the customer whether calibration or recalibration of the driver assistance system is required as part of the glass work. Failing to give that notice breaks the law. It may come electronically, or in writing in at least 12-point type. Because the notice must say whether, you should get an answer either way.
A yes tells you the recalibration belongs in the plan and on the invoice. A no is just as useful to have in writing. If the notice comes on paper in small print at the foot of a work order, check the size, since anything under 12-point does not meet the rule.
The question that follows is what happens if the recalibration cannot be finished at the visit. A.R.S. 20-463.02(D) answers it for Arizona jobs. If a recalibration was not performed, or did not succeed, the facility must tell the customer and the customer's insurer. That notice may be electronic or in writing, and it must say the recalibration failed or was not done. That notice is your record that the camera system has not yet been recalibrated after the glass work.
Keep it with the invoice and the itemized description. It is the document to point to when you arrange the follow-up visit. Fla. Stat. 559.920(18) covers whether recalibration is required, so ask a Florida shop to put a failed or skipped one in writing too. Our camera calibration service page covers how that work fits with a replacement.
Booking With an Installer Who Can Show the Paper Trail
Before you book, ask each company for the adhesive system name, how long it keeps job records, the drive-away time and its recalibration answer. Favor the one that answers with product names, record periods and written notices. In Florida, run the company name through the FDACS lookup first; in Arizona, ask for the itemized description before work starts. When you are ready, book a mobile replacement visit, or read how a visit at your car works on our mobile auto glass page.
Mobile windshield installer record questions
How long should a windshield installer keep a job record?
The AGRSS standard sets at least three years from the date the work was completed. For a replacement finished in October 2026, that means keeping it through at least October 2029. A company can keep it longer, so ask at booking whether you can get a copy of the record for your own file.
Can a Florida windshield invoice list the whole job as one lump price?
Fla. Stat. 559.911 asks for an itemized description of all labor, parts and merchandise supplied and the cost of each, so a single lump figure falls short. Anything supplied without cost or at a reduced cost because of a shop or manufacturer's warranty must be marked as such.
Who must be told if a windshield camera recalibration fails in Arizona?
Under A.R.S. 20-463.02(D), the auto glass facility must tell both the customer and the customer's insurer, electronically or in writing, that the recalibration was not successful or was not performed. Keep that notice with the invoice; it is your record when a follow-up visit is arranged.
