Engineering and construction firm website cost in Charleston: local agencies vs Kolonell (2026)

The verdict in three sentences

In Charleston, a website for an engineering and construction firm built by an agency costs, as a 2026 ballpark, between 12 000 and 50 000 USD, with Lowcountry studios at the lower end and Charlotte or Atlanta agencies that pitch regional contractors at the upper end. Kolonell builds the services, markets, project sheets, prequalification package and careers pages for a fixed price of 2 900 USD, 4 900 USD or 8 900 USD, with native English copy and a project manager available on Eastern Time. Kolonell does not shoot aerials or visit job sites, so if your superintendents already capture drone footage, the comparison tilts clearly in your favor.

What do Lowcountry agencies, freelancers and Kolonell charge a contractor?

The figures are prudent ballparks based on public rate cards of Charleston, Mount Pleasant and Columbia agencies, minimum project sizes on Clutch.co profiles across South Carolina, Charlotte and Atlanta, hourly rates published by local studios (often 100 to 175 USD per hour) and freelance profiles on Upwork. No figure is attributed to a named agency.

Choose a Charleston agency if you want someone to walk your job sites in Summerville and Daniel Island, run your trade show booth design and manage your social media in the same contract. Kolonell is a remote studio: Google Meet calls at Charleston hours and a written update every week, with a team in Senegal (GMT) four to five hours ahead of Eastern Time depending on the season. Payment by bank transfer or Wise, 50 % at kickoff and 50 % at delivery. See our international website offer.

What is the three-year cost?

Both columns use the same maintenance and hosting assumption after support. Kolonell maintenance after the support period is quoted on request; the figure is a hypothesis applied to both sides.

The agency figure includes no photography because both sides assume your own drone footage. If you need a professional shoot, add the same local cost to both columns.

What does a Charleston contractor or engineering firm need online?

The Charleston region builds a lot and builds in a demanding setting. Distribution centers and logistics buildings serve the port across Berkeley and Dorchester counties, manufacturing and aerospace suppliers expand around North Charleston, academic medical and health care projects continue on the peninsula, and residential growth keeps pushing out to Mount Pleasant, Summerville and the islands. Work on the historic peninsula often goes through the Board of Architectural Review, coastal projects must account for hurricane wind loads, storm surge and tidal water, and military work at Joint Base Charleston requires registration on SAM.gov. Owners and their project managers check the website before inviting a contractor to bid, and they look for proof of similar work, safety culture and capacity.

• Licenses, exactly as held. In South Carolina, engineers are licensed by the State Board of Registration for Professional Engineers and Surveyors, and general and mechanical contractors by the Contractor's Licensing Board, both under the Department of Labor, Licensing and Regulation, with license classifications and limits. Opening an office in Georgia brings Georgia's own licensing boards into play. State each license precisely and verify it with the board.
• Bonding and insurance, without exaggeration. Publish a bonding capacity statement only if your surety confirms the wording.
• Owner consent for references. Industrial and health care owners frequently restrict photos. Describe projects generically, such as a 200 000 square foot distribution center in Berkeley County, when you lack written approval.
• Field careers in Spanish. Many contractors want a Spanish version of the craft careers page. Kolonell writes English and French natively; Spanish copy is supplied by you or quoted separately.

Compliance, facts only. The ADA has been applied to websites in a number of court cases, and WCAG 2.1 AA is the usual technical reference. For federal contracts, check whether Section 508 requirements apply to what you deliver. Job applications sent through the site contain personal data, so publish a clear privacy notice; check with counsel whether any state privacy statute applies to you. This is not legal advice.

What should make you hesitate in a quote?

• Each new office priced as a separate site, with duplicated content that competes with itself in search results.
• A prequalification PDF that only the agency can update when your bonding or insurance changes.
• Hurricane or resilience claims the firm cannot document project by project.
• Field careers buried under office roles, when superintendents and foremen are your hardest hires.
• A domain or hosting account in the agency's name.
• Questions to ask: How do we add an office later, and at what price? Can our coordinator replace the prequalification file? Is the site checked against WCAG 2.1 AA? How large is a gallery page on a phone?

Mini case study

Illustrative example. Robert H. is CEO of a 70-person general contractor and construction manager based in North Charleston. The firm is opening an office in Savannah and wants owners there to see a regional builder, not a newcomer. A Charleston agency quotes 46 000 USD including two aerial shoots. One of Robert's superintendents is a licensed drone pilot and already captures progress footage, so the shoots are unnecessary.

• Agency without the shoots: about 40 000 USD, plus 2 500 USD for the Savannah pages, so 42 500 USD, about 14 weeks.
• Kolonell Premium with two office pages, a prequalification package and craft careers: 8 900 USD, usually 4 to 6 weeks.
• Difference: 33 600 USD, roughly what Robert budgets for the first year of a Savannah business development hire's travel and events.

If Robert also wanted trade show and social media management, a full-service local agency would be a fair alternative.
