Vinyl Siding Buying Guide
Profile Selection
Double 4" and Double 5" are most popular for efficiency. Dutch lap adds shadow lines for character. Board & batten provides a modern farmhouse look. Shake mimics cedar without the maintenance.
Thickness Matters
Thicker vinyl (0.044"+) resists dents, warping, and fading better. For coastal areas like Myrtle Beach, premium 0.046"+ vinyl withstands salt air and high winds. Economy grade works for sheds and outbuildings.
Insulated Vinyl
Foam-backed insulated siding adds R-2 to R-4 value, reducing energy bills 10-20%. It also provides a more rigid feel, reduces noise, and creates a flatter appearance than standard vinyl.
Color & Fade Resistance
Dark colors absorb more heat and may warp. Light to medium colors perform best in SC's sunny climate. Look for vinyl with fade protection warranties of 10+ years for lasting curb appeal.
Wind Resistance
Standard vinyl is rated for 110 MPH winds. For hurricane zones, look for enhanced locking systems rated to 180+ MPH. Proper installation with the correct nailing pattern is equally important.
Accessory Quality
Don't skimp on accessories. Cheap J-channel and corner posts deteriorate faster than the siding itself. Match accessory colors and brands to your siding for the best appearance and warranty coverage.
Vinyl Siding Calculator FAQ
How many panels of vinyl siding do I need?
Calculate your net wall area (gross area minus windows and doors), add 10-15% for waste, then divide by the square footage per panel. A Double 4" panel typically covers 8.33 sq ft (two 4" courses × 12.5' length). Our calculator does this math automatically.
How much does vinyl siding cost per square foot?
Vinyl siding materials typically cost $3-8 per square foot depending on quality grade and profile. Economy grade (0.040") runs $3-4, standard (0.044") is $4-6, and premium/insulated (0.046"+) costs $5-12 per sq ft. Installation adds $3-5 per sq ft for labor.
What vinyl siding thickness is best?
For residential homes, 0.044" is the minimum recommended thickness. Premium 0.046" vinyl offers better impact resistance and longer fade warranties. For coastal South Carolina with salt air and hurricanes, we recommend 0.046"+ thickness with enhanced wind ratings.
What accessories do I need for vinyl siding?
Essential accessories include: starter strip (bottom of walls), J-channel (around windows/doors), outside corner posts, inside corner posts, undersill/utility trim, and F-channel for soffits. You'll also need nails (ring shank or roofing), flashing, and possibly house wrap.
How long does vinyl siding last?
Quality vinyl siding lasts 20-40 years with minimal maintenance. In coastal areas like Myrtle Beach, expect 25-30 years with proper installation. Vinyl never needs painting, won't rot or be damaged by termites, and only requires occasional cleaning with a garden hose.
Can vinyl siding be installed over existing siding?
Yes, vinyl can often be installed over wood or aluminum siding if the surface is flat and in good condition. However, removing old siding allows for inspection of sheathing for rot or damage, adding house wrap for moisture protection, and achieving a flatter finished appearance.
