We Protect Your Investment So You Do Not Have to Lift a Finger.

You spent real money on that pergola, playset, bar, or gazebo. Now East Tennessee’s weather is working against it every single day. UV rays fade and crack the wood. Humidity feeds mold and mildew. Rain saturates unprotected surfaces. And before you know it, the structure that looked beautiful on installation day starts looking tired, gray, and neglected.

The good news: all of this is preventable. Foothills Custom Outdoors provides professional maintenance services for outdoor structures across Knoxville and East Tennessee, including power washing, wood staining, weather sealing, hardware inspection, and structural tightening. We keep your outdoor space looking sharp and performing safely, season after season, so you can enjoy it instead of worrying about it.

Why Outdoor Structures in East Tennessee Need Regular Maintenance

Knoxville’s climate is uniquely hard on outdoor wood and metal:

High humidity promotes mold growth, mildew staining, and accelerated wood rot, particularly on horizontal surfaces and at ground contact points.
Heavy seasonal rain saturates unprotected wood, swelling the grain and leading to cracks, warping, and structural weakening as the wood repeatedly absorbs and releases moisture.
Intense summer UV breaks down wood fibers and fades stain, turning a rich cedar or oak finish into a dull, splintering gray surface within a single season if left unprotected.
Temperature swings cause metal hardware to expand and contract, loosening bolts, screws, and brackets over time. This is especially problematic at structural connection points where loose hardware can lead to wobble, sag, or failure.

A structure that looks fine today can deteriorate rapidly without preventive care. Annual maintenance is the difference between a structure that lasts five years and one that lasts twenty.

Our Maintenance Services

Professional Power Washing

Dirt, pollen, mold, mildew, and algae build up on outdoor surfaces throughout the year. Left unchecked, these contaminants stain the wood, trap moisture, and create a breeding ground for decay. We use professional grade power washing equipment calibrated for the specific material (lower pressure for softwoods, higher for stone and concrete) to clean surfaces thoroughly without damaging the wood grain or finish.

Wood Staining and Re Staining

A quality exterior stain does more than improve appearance. It penetrates the wood and creates a barrier against moisture, UV, and insect activity. We apply professional grade, weather rated stains designed for East Tennessee conditions. For structures that have already grayed or faded, we prep the surface (cleaning, sanding, and brightening) before applying fresh stain to restore the original color and protection.

We recommend re staining every one to three years depending on the wood species, sun exposure, and the level of weather the structure receives.

Weather Sealing

Sealant protects wood from moisture absorption, which is the primary cause of rot, warping, and cracking in humid climates. We apply penetrating sealants to all exposed wood surfaces after cleaning and staining. For structures in high exposure areas (full sun, no overhead cover, heavy rain contact), we apply additional coats at critical points like end grain, joints, and ground contact areas.

Hardware Inspection and Tightening

Every bolt, screw, bracket, and anchor point on your structure is checked for tightness, corrosion, and structural integrity. We replace any hardware that is rusted, stripped, or failing and tighten all connections to the proper torque. This is especially important for playsets, pergolas, and any structure with moving components or overhead loads.

Structural Assessment

During every maintenance visit, we visually inspect the entire structure for signs of damage, wear, or developing problems. If we find early stage rot, cracking, insect activity, or anchoring issues, we flag them immediately and recommend corrective action before the problem becomes expensive.

Seasonal Maintenance Plans

We offer recurring maintenance programs so homeowners do not have to remember to schedule service or worry about falling behind on protection. Our seasonal plans typically include:

Spring: Full power wash, inspection, and hardware tightening after winter. Stain and seal touch ups as needed.
Fall: Pre winter inspection, sealing of exposed surfaces, and preparation of structures for cold weather moisture and occasional snow loads.

Homeowners can also request one time maintenance visits for specific needs or to prepare a structure for a special event.

What Happens When You Skip Maintenance

We see it every year: homeowners who invested in a beautiful outdoor structure but skipped the upkeep. Within two to three years, the results are predictable:

Wood turns gray and begins to splinter
Mold and mildew spread across surfaces and into joints
Hardware rusts and loosens
Structural connections weaken
The structure begins to sag, lean, or wobble
What was a minor maintenance need becomes a major repair bill

Regular maintenance costs a fraction of what repair or replacement costs. It is the most effective way to protect the money you have already spent.

Frequently Asked Questions: Maintenance Services

How often should I stain or seal my outdoor structure?

For most structures in East Tennessee, we recommend re staining and sealing every one to three years. Structures in full sun or heavy rain exposure may need attention more frequently. We assess your specific situation during each visit and recommend a schedule based on the actual condition of the wood.

Can you maintain a structure that was not installed by Foothills Custom Outdoors?

Yes. We provide maintenance services for outdoor structures regardless of who installed them. We inspect the structure, address any issues, and apply the same level of care we give to our own installations.

Do I really need power washing, or can I just seal over the dirt?

Applying stain or sealant over dirty, mold covered wood traps contaminants under the finish and accelerates decay. Proper cleaning before staining is essential for both appearance and protection. Skipping the cleaning step is one of the most common maintenance mistakes homeowners make.

What does a maintenance visit include?

A standard visit includes power washing, visual inspection, hardware tightening, and stain or sealant application. If we identify any damage or developing issues during the inspection, we report them to you with a recommendation. Maintenance visits are designed to be thorough, efficient, and minimally disruptive to your schedule.
