Question 1

Do you offer free estimates?

Accepted Answer

Yes — every estimate is free and there's no obligation. We'll visit your property, measure, and give you a written quote within a few business days.

Question 2

What areas do you serve?

Accepted Answer

Sioux Falls and the surrounding metro: Harrisburg, Tea, Brandon, Hartford, Crooks, Renner, Worthing, and outlying communities within roughly 45 minutes of Sioux Falls.

Question 3

How long has Dakota Seal been in business?

Accepted Answer

Since 1996 — nearly 30 years of asphalt and concrete maintenance in the Sioux Falls area. Locally owned and operated from day one.

Question 4

When is the best time of year for seal coating?

Accepted Answer

Late spring through early fall, once overnight lows stay above 50°F. Booking early in the season (March–April) locks in the best dates.

Question 5

How long does the parking lot need to be closed?

Accepted Answer

Most seal coating jobs require the lot to be closed overnight — typically applied late afternoon, open by the next morning. Larger lots may be done in phases so you're never fully closed.

Question 6

Do you handle ADA-compliant striping?

Accepted Answer

Absolutely. We design layouts that meet current ADA standards for accessible parking, access aisles, signage, and van-accessible spaces.

Question 7

Can you repair just part of my lot instead of replacing it?

Accepted Answer

In most cases, yes. Targeted patching, crack sealing, and seal coating can add 10–15 years to a tired lot at a fraction of replacement cost. We'll give you an honest assessment.

Question 8

What is TechCrete?

Accepted Answer

TechCrete is a polymer-modified concrete restoration system that bonds to existing concrete, cures in hours, and costs 30–40% less than tear-out and replacement. Ideal for loading docks, ramps, and high-traffic concrete areas.

Question 9

Are you insured?

Accepted Answer

Yes — fully insured for commercial and residential work. Certificates of insurance available on request.

Question 10

Do you work with property managers and HOAs?

Accepted Answer

Frequently. We work with property managers, HOAs, churches, schools, retail centers, and industrial properties throughout the metro. Multi-property maintenance contracts available.
