We almost exclusively install Gerkin windows, storm doors, and patio doors across Kansas City. Gerkin is manufactured in Storm Lake, Iowa - built specifically for Midwest climate conditions. Andersen is available for homeowners who request it by name.
Primary brand · Windows, storm doors, patio doors
Gerkin is our primary window brand for a reason. As a Midwest manufacturer they engineer their products specifically for the temperature swings, humidity levels, and wind loads that Kansas City homes experience - not for a national average climate. This means better long-term performance in the conditions your home actually faces.
We install the full Gerkin lineup including replacement windows in all standard styles, storm doors, and patio doors. Every Gerkin window we install comes standard with Low-e Argon glass unless the homeowner requests otherwise.
Available on request · Full installation to manufacturer spec
Andersen is one of the most recognised window brands in the United States and a strong product for homeowners who specifically want the Andersen name. We install Andersen windows to manufacturer specifications and can work with homeowners who have already selected Andersen as their preferred brand.
If you are comparing Gerkin and Andersen and not sure which direction to go, we are happy to walk through the differences during your consultation. Both are quality products and both perform well in the Kansas City climate.
An egress window allows a person to evacuate an area in an emergency. Before a window can be considered egress-compliant, specific requirements must be met. These requirements cover minimum opening width, height, and net clear opening area.
Egress windows are most commonly required in basement bedrooms, finished basement living spaces, and any sleeping area that is below grade. If you are finishing a basement and adding a bedroom, an egress window is typically required by code before the space can be used as a legal sleeping area.
We assess egress requirements during the site visit and confirm whether a window well is needed, what excavation is involved, and what the finished installation will look like from both inside and outside the home.
Any below-grade sleeping area must have at least one egress-compliant window. If you are finishing your basement and adding a bedroom or living space that will be used as a sleeping area, an egress window is required by Kansas City area building codes before the space can be permitted.
The frame material affects how the window performs thermally, how much maintenance it requires, and how long it lasts. Here is an honest breakdown of the four main options.
Wood
Vinyl
Fiberglass and Composite
Aluminum
The glass package affects energy efficiency, privacy, light transmission, and appearance. Low-e Argon comes standard on every window we install. Everything else is an upgrade option based on your specific needs.
Low-e Argon · Standard
Comes standard on every window we install unless requested otherwise. Low-e coating reflects heat back into the room in winter and blocks solar heat in summer. Argon gas between panes adds an additional layer of insulation. This is the energy efficiency package and it is included by default.
Tinted Glass
Reduces the amount of visible light that can pass through. Also adds an exterior accent effect - bronze tint is a popular choice that complements many Kansas City home exteriors.
Obscure Glass
Multiple options available to achieve different levels of obscurity. Most commonly used in bathrooms to allow natural light while maintaining privacy. Can also be used as a design element in half-windows or sash sections.
Beveled or Etched
Typically used on front entry doors or the centre window of a bay as a way to accent a specific window. Adds a decorative element without eliminating light transmission.
Grids and Muntins
Multiple design decisions: traditional or prairie configuration, profile and thickness of the grids, colour options including two-tone interior stain with solid exterior colour, and placement options including external removable grids or grids between the glass.
Blinds Between Glass
Some manufacturers offer blinds between the glass panes. Worth knowing: adding BBG removes the ability to include Argon gas, which is a major factor in energy efficiency. This trade-off is worth understanding before selecting this option.
Every window project involves one of two installation approaches. The right choice depends on the condition of the existing frame, the trim details you want, and your budget. We assess this during the site visit.
The existing window and frame are removed entirely down to the rough opening. New frame, new window, new trim. Best choice when the existing frame has rot, damage, or is not square. Allows full customisation of all trim details.
The existing frame stays. The new window slides into the existing opening. Faster and less disruptive than full frame replacement. Best choice when the existing frame is in good condition and the homeowner wants minimal interior and exterior disruption.
These are the details we cover with every homeowner before the installation date so there are no surprises on the day.
Alarm systems
We do not attach or reattach any alarm systems connected to windows. Alarm systems should be disconnected prior to our arrival on the scheduled installation date. Contact your alarm company in advance to arrange this.
Blinds, curtains, and window treatments
There is no guarantee that new windows will accommodate existing blinds or window treatments. All window treatments should be removed before the installation date. We can take them down and reinstall for a fee but cannot guarantee they will fit the new windows as they did before.
Wood rot
If your original windows were installed more than ten years ago, the redundancies used today may not have been done correctly at the time. Finding some wood rot during a window project is not uncommon. When we find it we photograph it immediately, notify the homeowner, and discuss the best course of action before proceeding. This is not included in the original estimate and is billed as time and material.
Replace windows before siding
If you are planning to replace both windows and siding, we recommend addressing windows first. Doing siding first means paying for window trim details twice and can create a less clean finished exterior. Coordinating both scopes at the right time saves money and produces a better result.
Screens
Many double hung, single hung, and slider windows now come standard with half screens only. Full screens are available as an upgrade. If full-screen coverage is important to you, specify this when ordering so it is included in your window package from the factory.
Locks and security
Most manufacturers include one lock per window as standard. Additional locks are available as an upgrade for added security. If security is a priority for specific windows in your home, let us know during the product discussion so we can specify the right hardware.
Acumen Renovations installs Gerkin windows, storm doors, and patio doors and Andersen Windows across Kansas City KS, Overland Park, Leawood, Shawnee, Lenexa, Olathe, Lawrence, and the surrounding metro area.
We almost exclusively install Gerkin windows, storm doors, and patio doors. Gerkin is a Midwest manufacturer whose products are built specifically for the temperature extremes and weather conditions Kansas City homes face. We also install Andersen Windows for homeowners who request that brand specifically. If you are not sure which brand is right for your project, we are happy to walk through the comparison during your consultation.
Full frame replacement removes everything - the existing window, frame, and trim - down to the rough opening. It gives you the most customisation options and is the right choice when the existing frame has rot, damage, or is not square. A pocket insert keeps the existing frame and slides the new window into the existing opening. It is faster, less disruptive, and more economical when the existing frame is in good condition. We assess which approach is appropriate during the site visit.
Yes. Every window we install comes standard with Low-e Argon glass unless the homeowner requests otherwise. Low-e coating manages heat transfer and Argon gas between the panes adds additional insulation. This is the energy efficiency package and we include it as standard rather than as an upgrade.
An egress window is a window that meets minimum size requirements to allow a person to evacuate in an emergency. Egress windows are required in any below-grade sleeping area. If you are finishing a basement and adding a bedroom or space that will be used for sleeping, Kansas City area building codes require at least one egress-compliant window before the space can be permitted. We assess egress requirements during the site visit.
Picture windows have the highest energy efficiency of all window types because they have no moving parts and no gaps for air infiltration. Casement windows are the best-performing operational window - when closed they seal against the frame tightly producing excellent thermal performance. Slider windows generally have the lowest performance rating of all operational window types. For Kansas City's climate, casement or double hung windows with Low-e Argon glass are our most common recommendation for performance-focused projects.
Windows first. If siding goes on before windows are replaced, you will pay for window trim details twice and the finished exterior will not look as clean. When both are being planned, coordinate them so windows are installed first and siding follows. We handle both scopes and can help you sequence the project correctly.
Yes. We install Gerkin storm doors and patio doors in addition to windows. Gerkin storm doors are available in full view, mid-view, and ventilating configurations. Patio doors are available in sliding and hinged options. If you are replacing windows and want to address doors at the same time, we can scope both as a single project.
