Seattle's Top Rated Website Design & Development

Your website design should set you apart from your competition and position you as a leader in your industry. It should clearly communicate your objectives and speak directly to your audience. Above all, it should lead visitors to a desired action and achieve the specific results defined for your organization.

Our website designs are custom and unique for each client - we don’t use templates! We tailor the entire solution to fit your communication goals, brand guidelines and target audience.



To create a great website design, we need to understand your business. We’ll partner with you to learn about your goals, competition, target audience, and preferences. We're a technology company, but our roots are in marketing, advertising and direct response, so we approach each project with these viewpoints in mind.



Once we understand more about your business, our designers begin the first design phase. We present unique web designs in each step, incorporating your feedback throughout the process. Check out our portfolio section for some great examples of Sandcastle's design work. Once you are satisfied with the design, it’s time to implement.



With approval of your web design, we begin the implementation process. Using highly optimized code and the latest industry standards, we build and deploy your website with cross-platform and cross-browser compatibility.


Customer Service

Throughout the entire process, we pride ourselves on customer service. We don't layer ourselves with "account managers." You will work directly with the people that are working on your project. We're committed to being honest and ethical, prompt and responsive in all of our interactions with you and your team. We hope you'll think of us as your in-house web design team.

Consistent Branding, Delivered to Multiple Target Devices.

Responsive design has become extremely popular due to its significant benefits in presenting your website across multiple devices consistently: large screen desktop monitors, laptops, tablets and a variety of mobile smart phones. This entails a specific approach that provides the ultimate viewing experience and easy navigation with minimum panning, sizing and scrolling across broad range of devices. Responsive web design requires additional efforts throughout the life cycle of the project, including design, development and testing. However, the benefits are well worth the trouble.


Responsive Web Design-Learn its Enormous Benefits

In today’s highly competitive world and web-based market scenarios, responsive web designs have finally emerged as one important aspect of profitable and successful business. When you opt for a responsive web design, you can experience the following advantages:

  • Improved User Experience – A responsive website is more user friendly. Your site visitors will click, explore and stay on your site longer. This will increase the likelihood that they’ll complete a purchase (or take some action if your site does not feature e-commerce). However, if your site is not easy to navigate, these visitors will likely get frustrated and leave to view your online competitors.

  • Preferred For Search Engine Optimization (SEO) – Responsive sites rank higher on search results. Websites with responsive designs are given preference and encouraged by search engines as they’re more user friendly for mobile devices. These devices are becoming the primary way people use the web.

  • One Site, Delivered To Multiple Devices – Responsive web design websites are "fluid" which means the same content flows across all devices and screen solutions. Both images and grids are fluid, so the content spreads out to occupy a reserved space and maintain its appearance. This fluidity obtains the same result smaller device screens, all with the same content. You manage one site, which will look a little bit different on the variety of devices that we've specified for your target audience.


No Templates! Your Website Needs To Reflect Your Specific Brand And Communication Goals

A custom designed website is essential to establishing your presence online. We feel that it’s extremely important that your website is unique, professional, and consistent with your branding.

We start by learning as much as we can about your company, your messaging and existing marketing materials. We want to capitalize on the imagery your target audience has already been exposed to. We’ll also evaluate your competition, identifying their strengths and weaknesses, so that we can design a site that clearly out shines them.

We’ll present you with a number of unique, custom website design options to choose from. Then, through a number of rounds of feedback and modifications we’ll arrive at a presentation that meets your requirements.

The technologies and platforms we use are all design agnostic, which means we have the complete freedom to make your site look and perform exactly like you want it. We don’t let technology dictate the way your site looks, that’s a design and marketing function, and we empower you to keep it that way.

Please see our portfolio of work in our What We've Done section. Additionally, here are a few samples of custom websites that demonstrate our design flexibility:
