Benefits

Wiring for Tomorrow’s Home

We design structured cabling that supports today’s gigabit service and tomorrow’s multi‑gig. Cat6/Cat6a home runs to a central patch panel enable 2.5–10GbE for high‑performance workstations, media servers, and Wi‑Fi 6/6E access points. We use heat‑rated cable and low‑loss connectors, plan wired backhaul for mesh systems, and specify active optical HDMI for long AV runs. Our layouts are scalable: add cameras, outdoor speakers, or a dedicated home office drop without re‑wiring the house.

Permits & Code Compliance Experts

Shaffer Construction handles permitting and inspections with the City of Glendale Building and Safety Division, following NFPA 70 (NEC), California Electrical Code, and TIA‑568 structured cabling standards. We submit clean drawings, coordinate HOA approvals, and schedule rough/final inspections. All penetrations in rated walls/ceilings are restored with UL‑listed firestop systems. Expect labeled terminations, documented test results, and a tidy panel that inspectors—and you—will appreciate.

Trusted Craftsmanship and Service

Our crews use premium materials: Cat6/Cat6a cable from reputable manufacturers, RG‑6 quad‑shield coax, keystone jacks and patch panels from Leviton/Ortronics class, CL2/CL3‑rated speaker wire, and in‑wall/optical HDMI for long runs. Cables are stapled and supported to code, with service loops at devices and Velcro‑managed bundles. We isolate low‑voltage from power to reduce interference, provide surge protection at the rack, and label everything so your system is maintainable for years.

Custom Connectivity Solutions

Every Glendale home is different. We start with a walk‑through, review your ISP handoff location, attic/crawlspace access, and preferred TV/office spots, then map cable paths that minimize wall damage. We design a central hub with a ventilated cabinet, patch panel, and switch, and plan wired backhaul to ceiling or wall‑mounted access points. For hillside and mid‑century homes, we often add conduit pathways for future pulls and seismic‑secure racks and displays.

Frequently Asked Questions

Do I need a permit for low‑voltage wiring in Glendale?+

Single‑family low‑voltage cabling can be permit‑exempt, but condos, multifamily units, and any work opening walls or penetrating fire‑rated assemblies often require permits. We confirm requirements with the City of Glendale Building and Safety Division, handle submittals, and schedule inspections if needed. HOAs near Brand Boulevard typically require prior approval for exterior devices and penetrations.

How long will my project take in Glendale?+

Most residential Data, Network & AV Wiring installs take 1–3 days once we start. If permits or HOA approvals are involved, expect 2–3 weeks for paperwork before installation. We’ll align work with any drywall or painting schedules and try to minimize downtime for your internet service.

Can you improve Wi‑Fi in multi‑level hillside homes?+

Yes. We design wired backhaul pathways and place ceiling/wall‑mounted access points on each level to overcome stairwells, thick walls, and long runs. We use Cat6/Cat6a and heat‑rated materials for hot attics common in Glendale summers, and we validate coverage with post‑install testing so patios and ADUs get signal too.

Will you coordinate with my ISP (Spectrum or AT&T Fiber)?+

We don’t replace your ISP, but we optimize your in‑home network. We relocate or extend the ISP handoff to a central rack, install a proper switch and access points, and label everything. When AT&T or Spectrum arrives, they can plug into a clean demarcation and your internal network will be ready to deliver full speeds.

What if my home has plaster walls or limited access?+

We use minimally invasive techniques—existing chases, closets, baseboards, and attic/crawl paths—to reduce wall openings. For tough routes, we add discrete conduit (paintable or in attic) to future‑proof. In historic Rossmoyne or similar areas, we can design solutions that avoid exterior visual impact and meet preservation expectations.
