TLM Irrigation & Lighting is a South Carolina-based landscaping company that specializes in outdoor irrigation systems and landscape lighting design and installation. They work with residential and commercial properties across the state, handling everything from sprinkler system design and repair to outdoor lighting that highlights landscaping features and improves property visibility after dark.

The company focuses on two main services: getting water to your landscape efficiently through properly designed irrigation, and creating outdoor lighting that serves both practical and aesthetic purposes. Whether you need a new system installed, an existing one repaired, or a complete landscape lighting overhaul, TLM handles the planning, installation, and maintenance.

Irrigation system design and installation

A well-designed irrigation system delivers water where it is needed without runoff or waste. TLM starts by evaluating your property—the layout, plant types, soil drainage, and sun exposure—to create a system that fits your landscape rather than forcing your landscape to fit a generic setup. This assessment determines how many zones you need, where sprinkler heads should go, and what water pressure and flow rate will work best.

Installation includes running lines underground or above ground depending on your property, placing sprinkler heads at the correct spacing and angle, and connecting everything to a controller that lets you set watering schedules. TLM can also integrate smart controllers that adjust watering based on rainfall and temperature, which saves water and money over time. Once the system is running, they offer maintenance and repair services—fixing leaks, replacing broken heads, and adjusting zones as your landscape changes.

Landscape lighting for safety and appearance

Outdoor lighting serves multiple purposes: it makes pathways and steps safer to navigate at night, deters trespassers by eliminating dark corners, and highlights trees, shrubs, and architectural details that you want to showcase. TLM designs lighting plans that balance these goals, placing fixtures to avoid glare while creating the mood and visibility you want.

Common landscape lighting options include uplighting (shining light up at trees or walls), downlighting (casting light down from above), path lights along walkways, and accent lights on specific features. TLM can install low-voltage LED systems, which use less electricity than traditional outdoor lights and last longer. They handle the wiring, transformer installation, and any necessary permits, then maintain the system as bulbs age or fixtures need adjustment.

How to contact TLM and what to expect

To get your free guide, contact TLM Irrigation & Lighting directly by phone or through their website to describe your project and request a site visit. During the visit, a designer or technician walks your property, takes measurements, discusses what you want to achieve, and answers questions about cost and timeline. They will provide a written estimate before any work begins.

Turnaround time varies depending on the size of the project and current demand. A simple repair might be completed within days, while a full irrigation system installation or comprehensive landscape lighting design may take weeks from estimate to completion. TLM can usually schedule consultations within a few days and will give you a realistic timeline once they understand the scope of work.

Irrigation maintenance and seasonal adjustments

After installation, irrigation systems need regular attention to perform well. TLM offers maintenance plans that include spring startup (pressurizing lines and checking for winter damage), summer adjustments (tweaking zones if plants are over- or under-watered), and fall shutdown (draining lines to prevent freeze damage). They also respond to emergency repairs—a burst line, a broken sprinkler head, or a controller malfunction.

South Carolina's climate means your irrigation needs change throughout the year. Spring and early summer typically require more frequent watering, while fall and winter need less. TLM can reprogram your controller seasonally or install a smart system that does it automatically based on weather data. Regular maintenance also catches small problems before they become expensive failures.

Lighting maintenance and upgrades

Landscape lighting systems need occasional upkeep as bulbs burn out, fixtures shift, or you decide you want to change the look. TLM handles bulb replacement, fixture repair, and repositioning lights if your landscape has grown or changed. If your system uses older halogen or incandescent bulbs, they can upgrade you to LED, which reduces your electric bill and means less frequent bulb changes.

Over time, you may want to expand your lighting—adding lights to a new patio, highlighting a new tree, or improving visibility in a dark corner. TLM can assess your existing system and add fixtures without rewiring everything, or redesign the whole system if you want a major change. They work with your budget and can prioritize which areas to light first.

Frequently Asked Questions

How much does a new irrigation system cost?

Cost depends on your property size, soil type, water source, and system complexity. A small residential system might cost less than a large commercial installation with multiple zones and smart controls. TLM provides a written estimate after the site visit, so you know the price before committing.

Can TLM repair an irrigation system installed by someone else?

Yes. TLM repairs systems regardless of who installed them. Bring any documentation you have about your system (manuals, zone maps, controller settings), and they will diagnose the problem and discuss repair options with you.

Is landscape lighting expensive to run?

LED landscape lighting uses significantly less electricity than older bulb types, so monthly costs are modest. TLM can show you the difference between LED and traditional options and help you choose fixtures that fit your budget and energy goals.

What happens to my irrigation system in winter?

In South Carolina, winter shutdown protects your system from freeze damage. TLM drains lines and blows out water with compressed air so ice cannot form inside pipes and crack them. Spring startup reverses the process, and they check for any damage that occurred over winter.

Do I need a permit for irrigation or lighting installation?

Permit requirements vary by county and city in South Carolina. TLM knows local codes and can tell you whether your project needs a permit. They handle permit paperwork as part of their service when required.
