Built to last
Every ZLM project comes with our own warranty on our work, and most products we install also carry a warranty from the company that makes them. All ZLM warranty periods start on the date your project is completed.

What's included
ZLM warranty: For three years after completion, if anything we installed has a problem — settling, shifting, loose pavers or wall units — we fix it at no charge for materials or labor.
After 3 years: repairs are billed at a $250 service call plus $120 per hour.
ZLM warranty: For ten years after completion, we will repair any problem caused by how we built your deck, pergola, pavilion or other structure.
After 10 years: repairs are billed at a $250 service call plus $120 per hour.
ZLM warranty: If caulk, paint or stain peels, cracks or fails within one year because of how it was applied, we will redo it at no charge.
After 1 year: the Sherwin-Williams product warranty applies, depending on the product used — for example, Emerald exterior paint carries a lifetime limited warranty and SuperDeck waterborne deck stains carry a 3-year limited warranty. Your invoice lists the products used on your project.
Stain on decks and other walking surfaces wears with use and weather and needs periodic recoating. That's normal upkeep, not a warranty issue.
ZLM warranty: Lifetime warranty on the fixtures and product, 50,000 hours on the LED bulbs, and 1 year on labor. For the first year, we come out and fix it at no charge.
After 1 year: product and bulbs are still covered, but service visits are billed at a $250 service call plus $120 per hour.
Manufacturer warranty, AMP Lighting: Lifetime warranty on brass fixtures, LED bulbs, and transformer cores and housings.
ZLM warranty: 1 year on the system and installation.
After 1 year: the manufacturer warranty covers the equipment, and service visits are billed at a $250 service call plus $120 per hour.
ZLM warranty: 1 year on the screens and installation.
After 1 year: the manufacturer warranty covers the product, and service visits are billed at a $250 service call plus $120 per hour.
Manufacturer warranty, Progressive Screens: Limited warranty against defects in materials and workmanship, for the original purchaser only (not transferable).
Not covered: normal wear, storm or flying-debris damage, skipped cleaning and maintenance, modifications or unauthorized repairs, and use outside normal operating conditions.
ZLM warranty: 1 year on the pergola and installation.
After 1 year: the manufacturer warranty covers the product, and service visits are billed at a $250 service call plus $120 per hour.
Azenco supplies replacement parts; labor isn't included. You must register your pergola within 60 days of installation to activate coverage — Azenco emails a registration form after installation, or register at azenco-outdoor.com/warranty. Azenco's warranty team: warranty@azenco-outdoor.com or (305) 306-3204.
ZLM warranty: For three years after completion, we will repair any problem with the pool finish caused by how we applied it.
Manufacturer warranty, NPT StoneScapes: 10-year limited warranty on the finish materials for every homeowner whose pool is finished with StoneScapes, extended to a lifetime limited warranty when applied by a StoneScapes Approved Applicator. NPT's warranty covers its materials, not installation.
Start-up care matters. Brush the whole pool daily for the first month, keep the water balanced, don't use an automatic or robotic cleaner for the first 14 days, and wait at least 14 days before heating the water. Discoloration, mottling or staining caused by water chemistry, chemical misuse or skipped start-up care isn't covered.
Keep it looking its best
A little routine care keeps everything looking good and keeps your warranties valid. Most manufacturer warranties require the product to be used and maintained the way the manufacturer recommends.
The fine print
These apply to the ZLM warranty in every category. Manufacturers have their own exclusions in their full warranty terms.
