Policies — Shipping, Warranty, Payment, Communications
Effective date: 8/1/2026. These policies apply to all services and parts provided by Precision DPF Services at our Katy, TX and New Caney, TX locations.
Shipping Policy
Inbound filters. Customers may ship DPFs, DOCs, and other aftertreatment components to us for cleaning and testing. Please drain and bag components before boxing, include your contact information and a description of the concern inside the package, and ship to:
Precision DPF Services - 3740 N Mason Rd, Ste E Katy, TX 77449
Call us before shipping so we can log your inbound part and schedule it for service on arrival.
Freight and shipping costs. Unless otherwise agreed in writing, the customer is responsible for inbound and outbound shipping costs. We will select an appropriate carrier and packaging for return shipment; expedited shipping is available at the customer's request and expense.
Packaging and damage. Diesel particulate filters are ceramic-core components and must be packed to withstand freight handling. We are not responsible for damage that occurs in transit to our facility. Parts we ship out are professionally packaged; if a shipment arrives damaged, note the damage with the carrier at delivery, keep all packaging, and contact us within [2] business days so we can file the carrier claim with you.
Turnaround. Standard cleaning turnaround is [1–2] business days from receipt, plus transit time. We will contact you with results and any findings before return shipment.
Warranty Policy
Cleaning services. Our cleaning and testing workmanship is guaranteed. Every filter we service is flow-tested before and after cleaning, and your service report documents the measured results. If a filter we cleaned does not perform to the documented post-cleaning specification, return it within [30] days and we will re-clean it at no charge.
Limits of the cleaning warranty. Cleaning restores flow through the existing filter substrate — it cannot repair a filter that is cracked, melted, delaminated, or otherwise physically failed. If we discover substrate damage during inspection or cleaning, we will document it (with photos), notify you before proceeding, and discuss replacement options. Pre-existing substrate damage, damage caused by continued operation of a failed engine component (injectors, turbo, EGR, coolant intrusion), and damage occurring after the filter leaves our facility are not covered by the cleaning warranty.
Replacement parts. New aftermarket filters and components we sell carry the manufacturer's warranty, typically [1 year] from the date of sale against manufacturing defects. Warranty claims require the original invoice and are subject to the manufacturer's inspection and approval. Gaskets, clamps, and other installation hardware are warranted against manufacturing defects only.
What voids a warranty. Warranties do not cover failures caused by underlying engine or aftertreatment system faults that are not corrected, improper installation, physical abuse, or modification of the part. Correcting the root cause that loaded or damaged the filter is the customer's responsibility — we will document findings that indicate an upstream problem on your service report.
Unclaimed parts. Filters and parts left with us more than [60] days after we notify you that work is complete may be treated as abandoned and disposed of or recycled.
Payment Policy
Payment is due when work is complete unless credit terms have been established in advance and confirmed in writing. We accept major credit and debit cards, ACH/bank transfer, business checks, and cash.
Estimates and approval. Work proceeds on your approval of the estimate. If inspection or testing reveals additional needed work, we will contact you for approval before performing it.
Deposits and special orders. Special-order parts may require a deposit of [50]% at the time of order. Deposits on special-order parts are non-refundable once the order is placed with the supplier.
Fleet and commercial accounts. Established fleet accounts may be invoiced with terms of Net 15 or Net 30 upon credit approval. Past-due balances may accrue a late charge of [1.5]% per month, and parts and filters may be held until the account is current.
Returned payments. Returned checks and failed ACH payments are subject to a [$35] fee.
Texting & Communications Policy
Texting is optional. You can get an estimate, have your vehicle or filter serviced, and pay your invoice without agreeing to receive text messages. Giving us your phone number so we can call you about your service does not sign you up for texts. Consent to receive text messages is not a condition of purchasing any goods or services from Precision DPF Services.
How you opt in. We only send you text messages if you have separately and specifically chosen to receive them, by one of these methods:
Checking the optional "Yes — text me service updates about my vehicle" box on our in-shop sign-in form. The box is unchecked unless you check it, and you can complete check-in without checking it.
Texting SUBSCRIBE to 346-687-1006 from your mobile phone.
Asking us, in person or in writing, to text you about your service.
We record the date, time, and method of your opt-in on your customer record.
What you'll receive. Program name: Precision DPF Services — Service Updates. Messages are about your service: your filter or part has arrived, testing results or your service report are ready, your estimate or invoice is available to view, work is approved or complete, your vehicle or part is ready for pickup or has shipped, appointment reminders, and replies to questions you text us. Message frequency varies with your service activity — typically [1–10] messages per service visit. Message and data rates may apply.
Promotional texts. We do not send promotional or marketing texts unless you have separately opted in to them, and you can stop those at any time without affecting service-update messages.
Opting out. Reply STOP to any message at any time to stop receiving texts. You will receive one final message confirming your opt-out, and we will not text you again unless you opt in again. Reply HELP for help, or contact us at 346-687-1006 or info@precisiondpf.com.
Phone and email. If you do not opt in to texting, or you opt out, we will contact you by phone or email for required service communications (approvals, results, and pickup notices). You will never miss a service update because you declined texts.
Privacy. We do not sell or share your mobile number, your opt-in consent, or your contact information with third parties or affiliates for their marketing purposes. Carriers are not liable for delayed or undelivered messages. See our Privacy Policy and Terms and Conditions for details on how we handle your information.
