How To Put An Egress Window In A Basement
If you're because a basement renovation as a way to expand your living space, don't be surprised if your building-codes office has something to say virtually it–peculiarly if a new bedroom is office of your plan. Without an egress window in case of fire, regulations simply won't allow a basement bedroom. And because this ruling is fairly recent in many parts of the country, most existing basements were not built with egress windows. Information technology's a conundrum that could keep you cramped for space, with all the space you need right under your feet.
Thankfully, yous needn't exist restricted by the basement your house was built with. You can solve the problem by cut a large opening in a basement wall and adding a window that meets code requirements for egress. You'll find contractors willing to do this work, often for between $2000 and $3000, or you might consider doing it yourself. Well-nigh $500 and two days of work for two people will usually finish the job. While this is clearly a downwards-and-dirty project, there's naught particularly complicated about information technology, and the savings can be substantial.
What will you become for your investment? The added low-cal let in by the new, deep window can eliminate the night and dank atmosphere so mutual to earlier basement finishes. The sensory difference can be remarkable. In basements, more than than anywhere else, light is a critical design element.
Of course, the principal do good of a deep window is egress–an hands accessible opening through which y'all can escape or a firefighter can enter in the event of a basement fire. Basement fires are mutual, so this is actually more than a code issue. And of course, what'southward healthy will be good for the adjacent owner likewise. With an actress legal bedroom, y'all could recover 10 to xx times your window installation costs when you eventually sell your home.
Code Requirements
Local regulations vary, and then you'll demand to outset with a visit to your codes assistants office. With minor variances, here's what you'll find.
To begin, not all basement rooms demand a legal egress window, simply certainly no basement bedrooms will be allowed without one. And if information technology has occurred to you to call a given room a den before the inspection and a sleeping room after, well, let's just say that this isn't a very original idea. Today, whatsoever bedchamber-sized room with a closet is considered a bedroom, no matter what the blueprint says.
As for size requirements, expect to need a window with an opening of v.7 sq. ft. Some codes count the drinking glass area, while others measure the surface area with the window open. In any case, a vertical casement window with 6 sq. ft. of access is a proficient choice for a retrofit installation.
The peak of the window installation is too important. The bottom of the window opening should be no more than 44 in. off the floor. Outside, an oversize window well is required. It volition need to be at least 36 in. broad and extend 36 in. out from the window. The window well summit is also limited to 44 in., every bit measured from the well floor. If a deep basement forces a deeper window well, most codes will allow a concrete block on the floor of the well to serve as a step, as long as information technology doesn't interfere with the window's opening.
Our Project And Yours
Our installation was office of a larger basement renovation in a fifty-twelvemonth-quondam, 2-chamber home. We placed the egress window in a new basement bedroom, in place of an original small window. Yous don't have to piece of work with an existing window, simply it'south vastly easier. Our walls were fabricated of concrete blocks, which are substantially easier to cutting than poured concrete walls. We limited the width of our window opening to the bridge of ii blocks, or 32 in. To fit this opening, we chose a Pella ProLine model PCI-25, which is a aluminum-clad casement window (Pella Corp., 102 Principal St., Pella, IA 50219). This window requires a 29 ten 41-in. rough opening, and costs near $180.
A wider window would take required a structural header under the sill. The header would have lowered the placement of the window and created an outside trim problem. Our block wall was topped with a 4-in. cap cake, bringing the vertical dimension of our cutout equal to five viii-in.-loftier courses plus the cap block. Defective the cap block at the elevation, y'all would demand to cut down six courses and lay two four-in. blocks in the lesser of the opening.
We scored the blocks with a concrete demolition saw and knocked the pieces out with a hammer. We then lined the opening with a box fabricated of pressure level-treated 2 10 8s. To arrange a tight fit, we had the summit and ane sidepiece of the box lumber milled to 1 1/four in. This left plenty room to slide the window in identify and add insulation betwixt the window frame and box.
We also opted for a lawmaking-approved, galvanized-steel window well (near $190). It was costly, simply cut downward on labor. For half the money, yous might build the well out of mural timbers or stones.
Step ane: Cutting The Opening
First, dig a big hole next to the foundation that's at least 6 in. deeper than the bottom of the hereafter window and about 48 in. square. Clean the foundation wall as best you lot tin and mark the perimeter of the opening with a grease pencil or chalk. Then, use a concrete demolition saw to make the cuts. Our toll to hire the saw was nigh $18 for half a day.
At that place'southward no getting around it: A concrete saw is an ugly, unwieldy tool that creates an enormous cloud of dust. And so go at it slowly and wearable full center protection and a tight-fitting dust mask. While there'south nothing particularly difficult about it, cutting and removing physical is messy and can be intimidating. If you don't feel up to the work, hire a professional to do this part of the job, especially if yous're dealing with poured physical walls.
Brand your beginning pass only well-nigh 1/4 in. deep and concentrate on making a direct line. Once you've established a pathway for the saw bract, you can focus on cutting deeper. With concrete block, a 1-in.-deep score is often acceptable. For a solid physical wall, try to end with a cut at least iii in. deep–ideally, the cut should extend halfway through the wall.
Step 2: Installing the Window
When you've removed all the blocks and chiseled away any obstructing mortar, build the pressure-treated box to fit the opening. Apply construction adhesive to those surfaces of the opening that volition mate with the box. Press the box in identify and so that its outer border is flush with the outside of the block wall.
Step 3: Cutting The Opening
With the opening cutting on both sides, starting time borer the upper blocks with a hammer until they either break loose whole or crumble in pieces. In our example, the quondam window couldn't be freed until the blocks were smashed.
Step iv: Installing the Window
When you've removed all the blocks and chiseled away whatever obstructing mortar, build the force per unit area-treated box to fit the opening. Apply construction agglutinative to those surfaces of the opening that will mate with the box. Press the box in place and then that its outer edge is flush with the outside of the block wall.
Step five: Installing the Window
Then, nail the pinnacle of the box to the sill plate and secure the side and bottom members to the wall with hardened concrete nails, or a pulverization-loaded driving tool, such as a Ramset, and two one/2-in. nails. To avert shattering the blocks' webbing, drive the nails into the mortar joints.
Step 6: Installing the Window
Nosotros opted for a window without attached exterior molding considering we needed actress-wide trim to cover the seam betwixt the pressure level-treated box and the basement wall. At the height of the window, the wider trim extends into the siding. For a job with wooden clapboard siding like ours, first measure out and marking the siding for the inset trim at the top of the opening. Cut along the lines with a round saw set up for a ane/ii-in.-deep cutting and use a sharp chisel to complete the cuts in the corners.
Step 7: Installing the Window
A typical untrimmed window has metallic fins on each edge that act as nailing tabs for securing the window to the surrounding framework. To install the window, get-go fold the fins out. Then, prepare the window bated and utilize a generous bead of caulk to the box perimeter.
Step 8: Installing the Window
Identify the window in the opening and have a helper on the inside center and level information technology while you drive galvanized nails through the mounting fins and into the surrounding box.
Footstep 9: Installing the Window
With the window nailed in identify, mix a small amount of mortar and fill the gap betwixt the wall and the box, and whatever cracks in the physical that were acquired by sabotage.
Footstep ten: Installing the Window
To finish the installation on the outside, cut the top trim to fit, press it into the siding recess and smash information technology in place.
Step 11: Installing the Window
And so measure out and cutting the trim for the sides and bottom of the window and blast these pieces in place.

Finally, caulk the seams between the trim and basement wall, between the trim and siding, and all around the window. And so, prime and paint the trim.
Step 13: Setting The Window Well
Level the ground in forepart of the window and lower the well into the hole. Level the well side to side.
Step 14: Setting The Window Well
Drill through the openings along the wall flange and drive Tapcon screws, backed with washers, into the holes in the block. Backfill effectually the well, tamping the soil down in 6- to 8-in. steps. Finish past creating plenty of basis slope abroad from the well.
To handle backlog h2o during a heavy rain, yous'll need to provide adequate drainage. If your habitation's basement has a draintile and sump system, utilize a posthole digger to bore a hole virtually the wall that extends downwardly to the gravel around the ground. Fill up the pigsty with coarse gravel so that it can act as a spillway.
If no drainage system is in place, dig a 12-in.-deep trough forth the back of the well and fill it with gravel.
To finish the bottom of the well, add about three in. of gravel to the flooring to continue rain from splashing mud against the window.
Stride xv: Interior Finish
There are several means of trimming out a basement window, including using wood extension jambs, but a drywall wrap is near as elementary and inexpensive as information technology gets. Begin by framing the wall effectually the window. At the window, position the studs then the within perimeter of the framed opening lines up with the outer perimeter of the window casing.
Then, insulate betwixt the casing and the box. and nail metal J-dewdrop to the box on all iv sides.
Stride 16: Interior Terminate
Proceed the metal bead about i/16 in. away from the wooden casing. If necessary, add together cardboard shims betwixt the J-bead and box to bring the bead in line with the exterior of the window casing.
Step 17: Interior Finish
With the J-bead nailed in place, slide strips of 1/ii-in. drywall into the bead channel and blast or screw the strips to the framed opening.
Pace 18: Interior Finish
Caulk the ane/16-in. gap between the metallic bead and the casing.
Step 19: Interior Finish
And so, drywall the room and install corner dewdrop where the opening meets the wall. Finally, finish with drywall joint compound, and paint the jamb extensions with semigloss paint.
