Hardwood Floor Installation in Woodstock, GA

An addition, a sunroom conversion or a newly enclosed porch usually gets its floor last, after framing, roofing, drywall and paint. If that space will connect to rooms with wood floors, or you want one floor running through old and new, hardwood floor installation in Woodstock becomes the step that makes the addition feel like part of the house.

This page covers the timing, subfloor and height questions that come with joining new construction to an existing floor, along with transitions, stairs and protection.

Wait until the new space is closed in and conditioned

Subfloor panels in an addition often sit exposed to rain and humidity during framing. Wood flooring should not arrive until the space is weathertight, windows and doors are in, wet work such as drywall finishing and paint has dried, and the heating and cooling system is running at normal living conditions. Bringing boards into a damp shell is a frequent cause of gaps and cupping during the first year.

Once those conditions are met, we take moisture readings on the new subfloor and on the boards and compare them with the existing part of the house.

Checking the new subfloor

New framing is not automatically flat. Joists can vary in height, and panels that got wet during construction may have swollen at the edges. We check the subfloor with a straightedge, fasten any panels that move and sand or fill as needed. It also helps to confirm the joist direction in the addition, since it may run differently from the original house and influence which way the boards should go.

Matching the height of the existing floor

The most visible challenge is where old meets new. Ideally the addition was framed so the finished floors line up, but differences of a fraction of an inch are common. We measure at the opening before ordering. Small differences can be taken up with underlayment or by sanding a slight ridge, while larger ones may need a transition molding or an adjustment to the subfloor on one side.

Continuing the floor or marking the change

If the existing rooms have solid hardwood and you want the floor to run straight into the addition, the new boards should match the species and width, and they are woven into the old rows at the opening rather than butted along a straight line. Old and new are then sanded and finished together so the color is consistent, which our floor sanding and refinishing service takes care of.

If the existing floor is prefinished, a matching product may no longer be sold. In that case a deliberate threshold or a border at the opening often looks more intentional than a near match.

Slabs, crawl spaces and the right product

Additions are sometimes built on a concrete slab even when the original house sits over a crawl space. Solid boards are not suited to a slab unless a wood subfloor is built over it, so engineered hardwood in Woodstock is the usual choice there, and it can often be matched closely in species and color. For an addition over a crawl space, the ground cover and ventilation below are checked like any other part of the house.

Steps, expansion space and protection

A step between the original house and the addition gets a stair nosing that matches the floor, with the riser clad in wood or painted. Expansion space is left at the walls of the addition and at the joint with the old floor wherever a threshold is used. If other trades are still finishing inside the addition, the new floor is covered with breathable protection and heavy equipment is kept off it.

The estimate and the city office

The scope should state the conditions required before delivery, subfloor checks and corrections, the method of joining old and new floors, any refinishing of the existing floor, transitions, stair parts, trim and cleanup, with exclusions listed.

Woodstock is in Cherokee County. Since an addition involves structural work, ask the City of Woodstock Building & Safety Division about permits for the project; the same office can answer questions if the flooring stage brings plumbing or electrical changes.

Questions about flooring a home addition

How soon can hardwood go into a new addition?

Once the space is closed in, wet work like drywall compound and paint has dried, and the heating and cooling system has been running at normal living conditions. Then the subfloor and the flooring are checked with a moisture meter, and installation waits until the readings fall within the manufacturer’s range. Those conditions matter more than a date on the calendar.

What if the addition floor ends up higher than the old floor?

Small differences can often be handled by sanding down a slight ridge or adjusting the underlayment. When the new subfloor is noticeably higher, the options include planing or shimming at the joint, adding a transition molding or, in some cases, building up the old side. We measure before ordering so the fix is planned rather than improvised.

Should the boards in a Woodstock addition run the same way as in the house?

Usually, if the floor continues through a wide, open connection, since a change of direction there looks abrupt. If the addition connects through an ordinary doorway, a change can work, especially when its joists run the other way. Running boards across the joists gives the firmest fastening, so the layout is planned with both appearance and structure in mind.
