  • Why is signage important for my business?
    Signage is the best investment for you business. It gives you an identity. It not only helps customers locate your business, but it also provides 24 hour advertising.
  • What is vinyl lettering?
    Vinyl lettering includes lettering, numbering, or shapes that are individually cut out from a sheet of solid colored vinyl and then pre-spaced and placed onto pre-masked transfer tape. This allows the lettering to be easily installed as one piece, creating a clean and professional look. Vinyl letters can be applied to most any surface that is clean, smooth, nonporous, and wax-free.
  • Do I need a permit to install a sign?
    Regulations vary from city to city. You will need to check with your city's planning department for more information. In general, you do not need a permit to hang a banner, put graphics on a storefront window or set up a sandwich board, but there may be regulations to follow. We can provide you with the necessary drawings to submit to your city planning department if needed.
  • How long will it take to make my sign?
    Every project is different and is based on what is currently in process at our shop. If you are looking for a larger sign, a typical time frame is up to 10 business days after the proof is approved. We try to work with everyone and fit things in when we can. If you need something sooner, just ask and we will try to accommodate.
  • How long will my vinyl letters last?
    Most vinyl has a 5 to 7 year life span. We always us high performance vinyl for any project that will be outside and needs to last. Calendered vinyl (low cost, minimal life) is available for certain projects indoors.
  • What materials does Sierra Design Signs work with?
    We work with many different types of materials including polymetal, PVC, corrugated plastic (coroplast), lexan, vinyl banner, vinyl and more. The products used depends on the clients needs.
  • Do you wrap vehicles? How much does it cost?
    Yes. Prices vary depending on the type of vehicle and how much of the vehicle is wrapped. Give us a call for more information.
  • Does Sierra Design Signs install signs?
    Sierra Design Signs does not install signs, but we can give you recommendations if you need them. We do install vinyl lettering on location at your business.
  • How do I remove old letters and decals?
    To removing old decals, we recommend using a heat gun. If the graphic is on glass you can carefully use a razor blade, along with a heat gun. Do not use sharp or hard objects to scrape letters off non glass surfaces. This will scratch the surface. When using a heat gun, special care must be taken to not over heat the area you are working on. An adhesive remover can be used to clean up any remaining glue residue after the vinyl is removed.
  • Will magnetic signs harm my vehicle?
    As long as the area where the magnet will be applied is clean and dry without any protrusions or dents, it will not harm your vehicle. If moisture is trapped under the magnet, rust can occur. If using a magnet for a long period of time, you must remove and clean behind them weekly. If you do plan to use a magnet long-term, we recommend you get a vinyl decal instead. There is less maintenance and less risk of someone stealing the magnet.
  • How should I provide the artwork for my sign?
    Vector files are best, .EPS, .AI or .PDF. We want your sign to have the best resolution possible. Vector files can be sized up and down without sacrificing the quality. They can also be cut on a plotter. We can work with bitmap files, .JPG, .TIFF or .PSD, but your artwork must be in “real size” and at 150 dpi. If you do not have proper artwork, we can usually recreate it, but a design fee would apply. You can email us your “print ready” or “cut ready” artwork, mail us a CD-R, CD-RW, DVD or USB flash drive. You may also stop in with your artwork. If you have questions concerning your artwork feel free to contact us by phone or email. Not all .PDF files are created in vector format. If you are unsure, please send us the file and we will let you know.
  • Can you help with designing my sign?
    Yes. We can help you choose colors, fonts and how the text reads. If you already know what you want, but need it designed, we can do that too. The best signage with the biggest impact is short, sweet, and to the point.
  • Will I receive a proof?
    Yes. Visual proofs are created for every project we do, big or small. Our way of ensuring that we have everything correct and positioned according to your requirements is by sending a proof. You are responsible for making sure that spelling, sizes and quantities match your desired request. Your final approval on the proof ensures that you have carefully looked over every aspect of the design or project, and that all information and colors, ect. are accurate. It benefits everyone if errors are caught in the proofing process rather than after the job is completed and delivered.
  • What color will allow my sign to show up best on glass?
    We recommend white, or a very light color be used on glass as it has the best visibility and will show better. Vinyl can be applied either on the inside the glass or outside. We recommend the outside of the glass as it provides the best visibility.
  • Do you do other design work?
    Yes. We can design logos and all types of print material, including business cards, brochures, posters, flyers, rack cards, gift certificates, event tickets, door hangers and anything else you can think of. Design fees vary based on your project. Please contact us for more information. If we create a logo/brand identity for you, it must purchased from us before the artwork can be used outside of our shop. Once purchased we will email you your files in multiple formats. If you need a format that was not included, just ask.
  • How much do your signs cost?
    Price depends on size, material, complexity, etc. Give us a call 605-717-1415 for a custom quote! Square footage: This is the most basic cost driver. Bigger signs naturally require more material and labor, thus increasing the price. Complexity of shape: Simple rectangular signs are cost-effective, while custom shapes and intricate cutouts demand more precise work and potentially a higher price tag. Vinyl: Widely used for its affordability and versatility, vinyl comes in various grades and thicknesses, influencing the cost. Premium vinyl with longer lifespans will be pricier. Design fees: If you need custom design work, expect additional charges.
