Deck builders in Burnsville, MN

Homes in Burnsville have a median construction year of 1982, so a deck original to a typical house would now be about 44 years old — beyond the point where wood framing, fasteners and flashing can be assumed sound.

Many decks from the 1970s and 1980s were built before today's detailed deck provisions appeared in model codes. Common issues on decks of this age include corroded hangers, posts set directly in soil and ledger boards fastened with nails. Replacement is often the better value than repeated repairs.

That makes Burnsville's housing 6 years older than Dakota County as a whole, where the median home was built in 1988. Statewide, the median Minnesota home was built in 1979. Among the 62 covered Minnesota communities with Census data, Burnsville ranks #21 for oldest housing. In these ZIP codes, 7% of homes were built before 1960, 38% between 1960 and 1979, 42% between 1980 and 1999, and 13% since 2000 — the single largest group dates to the 1980s.

The nearest NOAA climate station with 1991–2020 normals is Farmington 3 Nw, about 7 miles away. It records an average of 150 days a year with a low at or below 32°F — a long, hard freezing season. On roughly 77 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Burnsville, that means footings must bear below the locally required frost depth to avoid heaving, and wood surfaces should be kept sealed so absorbed water doesn't split boards over winter. Synthetic decking tolerates freeze-thaw well but still needs the manufacturer's expansion gaps.

Snow is a major factor: the Farmington 3 Nw station averages about 41 inches a year. Framing has to carry snow load, stairs need a plan for winter use, and snow removal should be done with plastic-bladed shovels and ice-melt products the decking manufacturer allows.

Precipitation averages about 32.3 inches a year, falling on about 59 days with 0.1 inch or more — wet enough that drainage and flashing still matter, but dry spells also let wood surfaces dry out and check in the sun.

Summer heat is mild by comparison — average summer highs near 80°F and only about 7 days a year at 90°F or above — so board color can be chosen mostly on looks.

Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.

Burnsville has about 26,545 housing units across its covered ZIP codes. 45% are single-family detached homes, 19% are attached homes such as townhouses and rowhouses, and about 36% are in buildings with two or more units. Roughly 65% of occupied homes are owner-occupied.

The mix of detached homes and attached or multi-unit housing in Burnsville means deck projects range from large backyard decks to compact rear decks on narrow lots. Lot size, neighbors' sightlines and any association rules shape the right design.

• Replacement and major repair: about 17,820 homes (67%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
• Retrofit decks on older homes: about 5,228 homes (20%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
• Upgrades and expansions: about 1,341 homes (5%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.

With about 150 freezing days a year, the building window in Burnsville is compressed. Design, drawings and permits are usually handled in winter so footings can go in as soon as the ground allows in spring, and finishes like stain are applied before nights turn cold in fall.

For Burnsville, MN, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required.
